The Specific Angular Momentum of Early-Type Galaxies Unveiled by the Extended Planetary Nebula Spectrograph Survey

outreach@ing.iac.es (Javier Mendez) — Wed, 5 Jul 2023 22:00:00 GMT

Astronomers using data from the extended Planetary Nebula Spectrograph (ePN.S) early-type galaxy survey find that galaxies that are efficient in forming stars, like discs, are also efficient in retaining angular momentum. In early-type galaxies (ETGs), it is not so: there is a strong dependence as a function of total stellar mass, with the most massive galaxies being least efficient in forming stars and in retaining the angular momentum.

The Shortest-Period Binary Star System Known in the Galaxy is Resisting Inspiral

outreach@ing.iac.es (Javier Mendez) — Tue, 27 Jun 2023 17:00:00 GMT

A study led by James Munday (PhD student at the University of Warwick and support astronomer in the ING Studentship Programme 2022/2023) has recently been published that exploits optical photometry of HM Cancri, spanning more than 20 years. This long time-baseline has led to the determination of an incredibly precise orbital decay constraint for the system by timing the phasing of an optical modulation, which would not have been possible without the Isaac Newton Telescope, and the William Herschel Telescope. Uniquely of any binary star system, not only could the orbital decay of HM Cancri be measured at high precision, but the authors also discovered that HM Cancris inspiral is slowing down - not speeding up.

Astronomers Solve the 60-Year Mystery of How Quasars Are Ignited

outreach@ing.iac.es (Javier Mendez) — Wed, 26 Apr 2023 20:00:00 GMT

Scientists have unlocked one of the biggest mysteries of quasars - the brightest, most powerful objects in the Universe - by establishing that they are ignited by mergers between galaxies. First discovered 60 years ago, quasars can shine as brightly as a trillion stars packed into a volume the size of our Solar System.

First On-Sky Demonstration of Tomographic Scintillation Correction

outreach@ing.iac.es (Javier Mendez) — Mon, 6 Mar 2023 10:00:00 GMT

Scintillation noise can be the dominant noise source for photometric measurements of bright targets when observing with ground-based telescopes; no matter how large the telescope aperture, the effect enforces a photometric precision limit. It is unique to the conditions of the exact time of exposure, and is unpredictable a priori. If one could compensate for the scintillation noise, ground-based telescopes would effectively reach the same precision limit as telescopes in space. However, this is a significant challenge because scintillation is produced by high altitude turbulence and therefore the range of angles over which it is correlated is very small. Hence, it cannot be corrected with standard differential photometry.

White Dwarfs Become Magnetic As They Get Older

jma@ing.iac.es (Javier Mendez) — Fri, 24 Sep 2021 00:00:00 GMT

At least one out of four white dwarfs (WDs) will end its life as a magneti star, and therefore magnetic fields are an essential component of WD physics. New insights into the magnetism of degenerate stars from a recent analysis of a volume-limited sample of WDs have provided the best evidence obtained so far of how the frequency of magnetism in WDs correlates with age. This could help to explain the origin and evolution of magnetic fields in WDs.

The Extended Planetary Nebula Spectrograph (ePN.S) Early-type Galaxy Survey

jma@ing.iac.es (Javier Mendez) — Fri, 7 Dec 2018 11:00:00 GMT

Cosmological simulations predict that early-type galaxies (ETGs) are the results of extended mass accretion histories characterised by different numbers of mergers and merger mass ratios, their timing, and gas fractions. Depending on the sequence and nature of the mergers following the first phase of in-situ star formation, these accretion histories may leadto ETGs that have low or high mass halos, and that rotate fast or slow. In order to study the transition from the inner regions of ETGs to their outer accretion dominated halos, astronomers carried out a survey of 33 ETGs, the ePN.S sample, using planetary nebulae as tracers.

Searching for the Weakest Detectable Magnetic Fields in White Dwarfs

jma@ing.iac.es (Javier Mendez) — Fri, 23 Nov 2018 13:00:00 GMT

Magnetic fields are present in a large variety of stars across the Hertszprung-Russell diagram, during all evolutionary stages from pre-main sequence stars, to main sequence stars and evolved stars, up to the final stages when the star explodes as a supernova. Magnetic fields play important roles in stellar evolution. Even a fairly weak magnetic field can suppress convection in stellar atmospheres and affect cooling times of extremely old white dwarfs. While the effects of the magnetic fields are well observed and sometime even understood, the origin of stellar magnetic fields is often unknown, and we do not know how fields evolve as stars evolve.

Time Resolved Spectroscopy of Dust and Gas from Extrasolar Planetesimals

jma@ing.iac.es (Javier Mendez) — Fri, 2 Nov 2018 13:00:00 GMT

An international team of astronomers led by Marie Karjalainen (Isaac Newton Group of Telescopes, Spain), used electron-multiplying frame-transfer CCDs mounted on ISIS at the William Herschel Telescope to obtain time resolved spectroscopy of dust and gas from the extrasolar planetesimals orbiting WD 1145+017. The new results confirm previous findings showing the u'-band excess and a decrease in line absorption during transits. Both can be explained by an opaque body blocking a fraction of the gas disc causing the absorption, implying that the absorbing gas is between the white dwarf and the transiting objects.

First Results from Lucky Spectroscopy, an Equivalent Technique to Lucky Imaging

jma@ing.iac.es (Javier Mendez) — Mon, 29 Oct 2018 15:00:00 GMT

Following the principles of Lucky Imaging, a team of astronomers led by Jesus Maiz Apellaniz (Centro de Astrobiologia, Madrid) obtained Lucky Spectroscopy for five multiple massive-star systems on the nights of 2017 September 7 and 8. The spectra were obtained with the standard GOSSS-survey configuration using ISIS on the William Herschel Telescope, with some modifications (narrower slit and detector window, and tens of shorter exposures) to allow for lucky spatial separation of the individual component spectra. The spectra of delta Ori Aa+Ab and sigma Ori AaAb+B were successfully separated.

A Feasibility Study on the Photometric Detection of Quiescent Black Hole X-ray Binaries

jma@ing.iac.es (Javier Mendez) — Fri, 19 Oct 2018 11:00:00 GMT

Jorge Casares and Manuel A.P. Torres from the Instituto de Astrofisica de Canarias (IAC) have tested a novel photometric technique that can help unveil new quiescent BHXBs to unprecedented depths\ . They used an allocation of (IAC) Directors Discretionary Time with the instrument ACAM on the William Herschel Telescope (WHT), equipped with an OASIS r-band filter MR661 and two Halpha filters, kindly loaned by the Nordic Optical Telescope (NOT), to observe four dynamical BHXBs. This research opens the door to efficient selection of BHXBs since very deep gravitational wells are required to produce Halpha lines broader than FWHM > 2200 km/s. Monte Carlo simulations have shown that a cut-off at FWHM > 2200 km/s would allow selection of half of the BHXBs while rejecting other (dominant) populations of Halpha sources.

An Alternative Technique for Detecting Forming Exoplanets Around Young Stars

jma@ing.iac.es (Javier Mendez) — Tue, 16 Oct 2018 16:00:00 GMT

The large number of detected exoplanets around evolved stars sharply contrasts with the lack of detections of forming planets in protoplanetary disks around young stars, mainly because of the observational difficulties. Earlier this year, an international team of astronomers led by Ignacio Mendigutia (Centro de Astrobiologia, Spain), decided to use the ISIS spectrograph on the WHT to study the nature of the exoplanet LkCa15 b, by means of a technique called spectro-astrometry. This allowed them to derive not only the intensity spectrum around the H-alpha emission, but also the so called photocentre spectrum and the full width half maximum (FWHM) spectrum.

Approaching the Galactic Metallicity Floor with the Discovery of an Ultra-Metal-Poor Star

jma@ing.iac.es (Javier Mendez) — Mon, 8 Oct 2018 14:00:00 GMT

Recently, the survey team reported on the discovery of a particularly metal-poor star, Pristine 221.8781+9.7844, in the journal Monthly Notices of the Royal Astronomical Society.

Three Dynamically Distinct Stellar Populations in the Halo of M49

jma@ing.iac.es (Javier Mendez) — Mon, 1 Oct 2018 14:00:00 GMT

Using data obtained with the Planetary Nebula Spectrograph (PN.S) on the William Herschel Telescope (WHT), astronomers pursued an original investigation to constrain the mass of the satellite progenitors of the stars in the halos and determine a proxy for their dynamical age by measuring the motions along the lines of sight of hundreds of stars that are in a particular stage of their evolution: the Planetary Nebulae (PNe). Instead of a uniform stellar population floating in the gravitational potential of the galaxy, astronomers identified three populations, one associated with the smooth halo of M49, a sub-component of bright planetary nebulae associate with the recent accretion of a dwarf galaxy (VCC 1249), and a population of stars associated with the intra-group light.

Almost 500 Explosions Found in Galaxy Cores

jma@ing.iac.es (Javier Mendez) — Tue, 11 Sep 2018 07:00:00 GMT

A team of astronomers from SRON, Radboud University and the University of Cambridge have found out that by tweaking the existing automated system, Gaia can be used to detect hundreds of peculiar transients in the centres of galaxies. They found about 480 transients over a period of about a year. Their new method will be implemented in the system as soon as possible allowing astronomers to determine the nature of these events.

Evidence for Hot Clumpy Accretion Flow in a Transitional Millisecond Pulsar

jma@ing.iac.es (Javier Mendez) — Mon, 10 Sep 2018 14:00:00 GMT

Astronomers analysing simultaneous data obtained using the William Herschel Telescope and the Gran Telescopio Canarias, have been able to model the observed light curves of a transitional millisecond pulsar and conclude that the accretion of clumpy material through the magnetic barrier of the neutron star can produce the observed near-IR/optical variability and correlations.

Spectroscopy and Thermal Modelling of the First Interstellar Object 1I/2017 U1 ‘Oumuamua

jma@ing.iac.es (Javier Mendez) — Sun, 14 Jan 2018 15:00:00 GMT

Astronomers using ACAM on the William Herschel Telescope report the spectroscopic characterisation of ‘Oumuamua, finding it to be variable with time but similar to organically rich surfaces found in the outer Solar System. This is consistent with predictions of an insulating mantle produced by long-term cosmic ray exposure. This coating could have protected an ice-rich interior from being vaporised during its recent passage close to the Sun. An internal icy composition cannot therefore be ruled out by the lack of activity, even though ‘Oumuamua passed within 0.25 AU of the Sun.

A team of researchers led from the University of Warwick, UK is undertaking a transmission spectroscopy survey of hot Jupiters using the ACAM imager and spectrograph on the William Herschel Telescope. By observing spectroscopically an exoplanet's transit across the face of its host star the team is able to detect changes in opacity in the exoplanet's atmosphere as a function of wavelength. These early results have demonstrated the capabilities of ACAM to detect atmospheric opacity sources such as Rayleigh scattering, and to distinguish between clear and cloudy atmospheres with errors in the transmission spectrum of around 1 atmospheric scale height, comparable to Hubble Space Telescope.

The Puzzle of Ultra-Diffuse Galaxies

jma@ing.iac.es (Javier Mendez) — Fri, 25 Aug 2017 10:00:00 GMT

With the naked eye, we can see some 3000 stars in a dark night. However, if Earth would reside within an ultra-diffuse galaxy, we would only spot a few dozen stars on the sky. Galaxies of this type were either not able to produce more stars in the first place, or they got stripped of their stars by tidal forces. Intriguingly, though, larger telescopes and improved imaging techniques have recently led to the discovery of many ultra-diffuse galaxies in the harshest environments possible: galaxy clusters.

A Large Fraction of Rapidly-Growing Supermassive Black Holes Evade Census

jma@ing.iac.es (Javier Mendez) — Mon, 10 Jul 2017 16:00:00 GMT

Highly obscured and rapidly growing supermassive black holes (SMBH), known as active galactic nuclei (AGN), might represent the key phase when SMBH accreted most of their mass and when the relationship between galaxies and their central SMBHs was established. A new study by an international team of astronomers led by Dr Silvia Mateos from the Instituto de Fisica de Cantabria (CSIC-UC) in Spain, now suggests that many of the brightest SMBH may be escaping our detection as they hide in heavily obscured environments.

Superbubbles in the Interstellar Medium of the Antennae Galaxies

jma@ing.iac.es (Javier Mendez) — Mon, 08 May 2017 10:00:00 GMT

A team of scientists led by members of the Instituto de Astrofisica de Canarias (IAC), in collaboration with the Universidad Nacional Autonoma de Mexico (UNAM), have detected and measured a complete "carpet" of expanding bubbles in the interstellar medium of the "Antennae", a pair of galaxies in interaction which will eventually merge. The work, published in Monthy Notices of the Royal Astronomical Society is based on observations with GHaFaS on the William Herschel Telescope (WHT). This instrument is capable of making a map of the velocities of a complete galaxy using the emission from the ionized hydrogen in its interstellar medium.

Newly Discovered Planets Could Have Water on Their Surfaces

jma@ing.iac.es (Javier Mendez) — Thu, 23 Feb 2017 14:00:00 GMT

An international team of astronomers has found a system of seven potentially habitable planets orbiting a star 39 light years away, three of which could have water on their surfaces increasing the possibility they could host life. Using ground and space instruments and telescopes, including the ACAM imager on the William Herschel Telescope, the team identified the planets as they passed in front of the ultracool dwarf star known as TRAPPIST-1. The star has around eight per cent of the mass of the Sun and is no bigger than Jupiter.

New Light on Dark Matter Halos

jma@ing.iac.es (Javier Mendez) — Mon, 13 Feb 2017 15:00:00 GMT

For the past twenty years observers have been trying to test the effects of the predicted dark matter halos on the bars in barred galaxies. The basic idea is that according to simulation models which include the halos, these should have acted as a gravitational brake and slowed down the rotation of the bars during the lifetimes of galaxy discs.This could be tested by measuring the corotation radius corresponding to the bar, which is the radius at which the angular pattern speed of the bar is equal to the angular speed of the stars in the disc. The problem has been the difficulty of measuring the corotation radius. However, a group at the Instituto de Astrofisica de Canarias (IAC), devised a new method for corotation, using data from high resolution two-dimensional spectra taken with Fabry-Perot spectrographs, the most accurate among them GHaFaS on the William Herschel Telescope (WHT).

An Intrinsically Very Luminous Lensed High-Redshift Galaxy

jma@ing.iac.es (Javier Mendez) — Mon, 6 Feb 2017 11:00:00 GMT

An international team led by researchers from the Instituto de Astrofisica de Canarias (IAC) and the University of La Laguna (ULL) has discovered one of the brightest non-active galaxies in the early universe. This galaxy, called BG1429+1202, is a gravitationally lensed Lyman-Alpha Emitter (LAE) located at a redshift of 2.82, and intrinsically very luminous.

Turbulence Velocity Profile Characterization with Stereo-SCIDAR

jma@ing.iac.es (Javier Mendez) — Mon, 6 Feb 2017 11:00:00 GMT

Stereo-SCIDAR is a high-altitude resolution and high sensitivity optical turbulence profiler. By measuring the intensity pattern of two nearby stars astronomers can triangulate the altitude and strength of optical turbulence in the Earth's atmosphere. And by introducing a temporal delay between these two signals, they can also calculate the horizontal velocity of each layer. Stereo-SCIDAR was developed by Durham University, UK as part of the Canary Adaptive-Optics demonstrator project (CANARY) on the William Herschel Telescope, and it has been operated on the Isaac Newton Telescope for a total of 28 nights.

Lyman-alpha Giant Halos Around Early Milky Way Type Galaxies

jma@ing.iac.es (Javier Mendez) — Thu, 12 Jan 2017 11:00:00 GMT

Astronomers from the Universities of Lancaster in the UK and Leiden in the Netherlands report the discovery of giant halos around early Milky Way type galaxies which are composed of Lyman-alpha photons that have struggled to escape them.

A Deficit of Dark Matter in Elliptical Galaxies

jma@ing.iac.es (Javier Mendez) — Wed, 28 Dec 2016 15:00:00 GMT

The missing mass problem is a long-standing issue in astrophysics, being present in galaxies, cluster of galaxies and even at the cosmological scale. Astronomers from Taiwan have used archival data from PN.S and SAURON to study the internal dynamics of seven nearby elliptical galaxies, and report finding a dearth of dark matter. They conclude that the dynamics of these galaxies are well explained by MOdified Newtonian Dynamics (MOND).

A Radio Pulsing White Dwarf Binary Star

jma@ing.iac.es (Javier Mendez) — Thu, 28 Jul 2016 11:00:00 GMT

Astronomers have discovered a new type of exotic binary star. In the system AR Scorpii a rapidly spinning white dwarf star powers electrons up to almost the speed of light. These high energy particles release blasts of radiation that lash the companion red dwarf star, and cause the entire system to pulse dramatically every 1.97 minutes with radiation ranging from the ultraviolet to radio. The research is published in the journal Nature on 28 July 2016.

An Extremely Weak Magnetic Field in a White Dwarf

ING Telescopes Provide Unique Observations in Support of the ESA Rosetta Mission

jma@ing.iac.es (Javier Mendez) — Fri, 23 Oct 2015 20:00:00 GMT

The European Space Agency's Rosetta mission is currently exploring comet 67P/Churyumov-Gerasimenko. The Rosetta mission is a hugely ambitious endeavour - the first spacecraft to orbit a comet and follow it on its journey towards the Sun, accompanied by its lander, Philae, which made the first ever landing on a comet in November 2014. Observatories across the planet are supporting this mission, and the ING is playing an important part in this - especially in providing unique observations this year as the comet passed its closest point to the Sun and highest level of activity.

Binarity in Planetary Nebulae Gives Clues to Understand the Abundance Discrepancy Problem

jma@ing.iac.es (Javier Mendez) — Tue, 5 May 2015 09:00:00 GMT

Spectroscopic observations with the William Herschel Telescope of three planetary nebulae have shed new light on the abundance discrepancy problem. Astronomers from the Instituto de Astrof?sica de Canarias have shown that the largest abundance discrepancies (as high as 300 in certain positions in the nebula) are reached in planetary nebulae that have a close binary central star.

Mergers of Galaxy Clusters Can Trigger Star Formation

jma@ing.iac.es (Javier Mendez) — Mon, 4 May 2015 16:00:00 GMT

Galaxies are often found in clusters, which contain many "red and dead" members that stopped forming stars in the distant past. Over billions of years, galaxy clusters build up structure in the universe - merging with adjacent clusters. When this happens, there is a huge release of energy as the clusters collide. The resulting shock wave travels through the cluster like a tsunami, but until now there was no evidence that the galaxies themselves were affected very much.

First Near Earth Asteroids Discovered from La Palma

Direct Evidence for an Evolving Dust Cloud from an Exoplanet

jma@ing.iac.es (Javier Mendez) — Tue, 17 Mar 2015 10:00:00 GMT

Astronomers observed star KIC 12557548 on five nights in July 2013, using ULTRACAM on the William Herschel Telescope, to search for the colour dependence of the transit depth by KIC 12557548 b exoplanet. A clear transit signal was detected only on the first night. During the remaining four nights, the planet was in a quiescent period, with little or no dust cloud obscuring the star. As expected, the astronomers managed to observe differences in transit depths between three different bands on first night, with an increase in depth toward shorter wavelengths. This effect is consistent with extinction from the putative dust cloud surrounding the planet. Remaining nights allowed to constrain the size of the planet to less than 5.4 radii of Mercury.

First Observational Proof of Existence of a Double-Degenerate, Super-Chandrasekhar System

jma@ing.iac.es (Javier Mendez) — Fri, 20 Feb 2015 12:00:00 GMT

An international group of astronomers has found the first pair of white dwarfs with a total combined mass unequivocally above the Chandrasekhar limit of 1.4 solar masses. The orbital period of the system is 4.2 hours, which means that the stars are close enough to spiral in due to the emission of gravitational waves and eventually merge in about 700 million years. This finding, which has been published in Nature, provides observational support to the double-degenerate path of formation of type Ia supernovae, so far a theoretical possibility under ongoing debate.

One of Most Accurate Measurements of the Size of a Trans-Neptunian Object from a Stellar Occultation

jma@ing.iac.es (Javier Mendez) — Mon, 15 Dec 2014 15:00:00 GMT

Stellar occultations by minor bodies have been widely used to measure their sizes and constrain their shapes. One such event was observed at the William Herschel Telescope during the first hours of the night April 26, 2012 using ULTRACAM, a very fast camera able to obtain short exposures with very short overheads. They were able to measure a total eclipse duration of 20.87 seconds which translates into a chord of 415?1 km, one of the most accurate measurements obtained so far.

Astronomers Release Most Detailed Catalogue Ever Made of the Visible Milky Way

jma@ing.iac.es (Javier Mendez) — Tue, 16 Sep 2014 15:00:00 GMT

The production of the catalogue, IPHAS DR2 (the second release from the survey programme The INT Photometric H-alpha Survey of the Northern Galactic Plane? or IPHAS), is an example of modern astronomy's exploitation of 'big data' it contains information on the 219 million detected objects, each of which is summarised in 99 attributes. With this catalogue release, the team are offering the world community free access to measurements taken through two broad band filters capturing light at the red end of the visible spectrum, and in a narrowband capturing the brightest hydrogen emission line, H-alpha. The inclusion of H-alpha also enables exquisite imaging of the nebulae (glowing clouds of gas) found in greatest number within the disk of the Milky Way. The stellar density map illustrated here is derived from the longest (reddest) wavelength band in which the darkening effect of the dust is moderated in a way that brings out more of its structural detail, compared to maps built at shorter (bluer) wavelengths.

Instrumentation at the ING Telescopes

balcells@ing.iac.es (Marc Balcells) — Thu, 21 Aug 2014 20:00:00 GMT

Most users of the ING telescopes are well aware that our plans for the continued operation of the WHT and INT in the next decade call for the execution of massive spectroscopic surveys with WEAVE, a multi-fibre spectrograph now in construction for the WHT prime focus. Until the arrival of WEAVE, planned for late-2017, ING will continue to offer a broad range of instrumentation at the WHT and on the INT.

Random Bits, True and Unbiased, from Atmospheric Turbulence

jma@ing.iac.es (Javier Mendez) — Mon, 28 Jul 2014 08:00:00 GMT

Random numbers represent a fundamental ingredient for secure communications and numerical simulation as well as to games and in general to Information Science. Physical processes with intrinsic unpredictability may be exploited to generate genuine random numbers. The optical propagation in strong atmospheric turbulence is here taken to this purpose, by observing a laser beam after a 143 km free-space path, between the Jacobus Kapteyn Telescope on La Palma and the ESA Optical Ground Station at the Teide Observatory on Tenerife.

Discovery of Near Earth Asteroid 2014 LU14 with the Isaac Newton Telescope

jma@ing.iac.es (Javier Mendez) — Mon, 30 Jun 2014 21:00:00 GMT

2014 LU14 is the first ever Near Earth Asteroid (NEA) discovered using the Isaac Newton Telescope and from La Palma. This discovery is also the first reported by the EURONEAR network, a large collaboration founded by ING astronomer Ovidiu Vaduvescu which involves researchers and telescopes mostly based in European countries.

Spectro-Astrometry of V1515 Cygni with Adaptive Optics

jma@ing.iac.es (Javier Mendez) — Fri, 13 Jun 2014 19:00:00 GMT

Using the integral field spectrograph OASIS, at the William Herschel Telescope, combined with the adaptive optics module NAOMI, astronomers obtained optical observations of the FU Ori star V1515 Cyg with an angular resolution of 0.7 arcseconds (Gaussian core FWHM). From the analysis of the data they find evidence for the existence of a surrounding disk in V1515, being this one of the few spatial inferences of a disk observed in an FU Ori object.

Discovery of Circularly Polarised Light in a GRB Afterglow

jma@ing.iac.es (Javier Mendez) — Mon, 12 May 2014 19:00:00 GMT

A large international team led by Klaas Wiersema from the University of Leicester has discovered circularly polarised optical emission in the afterglow of GRB 121024A. The study, published in Nature, used data mainly from FORS2 on the VLT, but also ACAM on the WHT. The ACAM data allowed the team to correctly identify a break in the light curve that confirmed the long standing prediction that an abrupt change of 90 degrees in the GRB linear polarisation happens when the Lorentz factor of the outwards jet decreases below a critical value.

The Music of the Galaxies

jma@ing.iac.es (Javier Mendez) — Sat, 01 Mar 2014 16:00:00 GMT

Using Fabry-Perot optical interferometers, including GHaFaS on the William Herschel Telescope, and observing a sample of over a hundred nearby galaxies, astronomers have discovered that there are more density waves than predicted by theory, and that there are relations between them forming a complex pattern of resonances, which orchestrate the "Music of the Galaxies".

Instrument Rationalisation at ING - Community Input Sought

balcells@ing.iac.es (Marc Balcells) — Thu, 27 Feb 2014 16:00:00 GMT

In order to focus the observatory's resources on the WEAVE project, ING is planning a rationalisation of its instrument suite, which will likely imply a progressive reduction in the number of common-user instruments/modes offered at the WHT and INT, starting in semester 2015A.

RATS-Kepler: A Deep High-Cadence Survey of the Kepler Field

jma@ing.iac.es (Javier Mendez) — Thu, 30 Jan 2014 15:00:00 GMT

Before the launch of Kepler, an extensive programme to identify bright G/K dwarfs with minimial stellar activity was carried out by various groups internationally. Although a small number of photometric variability surveys were carried out pre-launch they were either not especially deep, did not have wide sky coverage or did not have a cadence shorter than a few minutes. To fill this gap a team of astronomers started a photometric variability survey (RATS-Kepler) in the summer of 2011 using the Wide Field Camera (WFC) on the Isaac Newton Telescope (INT). RATS-Kepler is complementary to the Kepler-INT-Survey.

The Rapid Assembly of an Elliptical Galaxy at a Redshift of 2.3

jma@ing.iac.es (Javier Mendez) — Tue, 28 May 2013 11:00:00 GMT

A rare encounter between two gas-rich galaxies indicates a solution to the problem of how giant elliptical galaxies developed so quickly in the early universe and why they stopped producing stars soon after.

Discovery of the First Isolated Compact Elliptical (cE) Galaxy

A Dust-Obscured Massive Maximum-Starburst Galaxy in the Early Universe

jma@ing.iac.es (Javier Mendez) — Fri, 19 Apr 2013 14:00:00 GMT

Astronomers of the Herschel Multi-tiered Extragalactic Survey (HerMES) project announce in the journal Nature the discovery of an unusually massive, maximum-starburst galaxy at a redshift of 6.34, or when the Universe was only 880 million years old. Because current theories of galaxy formation and evolution predict smaller galaxies with slower rates of star production in the early Universe, the detection of such a galaxy is challenging.

Professor Vikram Dhillon is Awarded the 2013 RAS Jackson-Gwilt Medal for the Development and Operation of ULTRACAM

jma@ing.iac.es (Javier Mendez) — Wed, 13 Feb 2013 09:00:00 GMT

ULTRACAM is an ultra-fast, triple-beam CCD camera designed to study astrophysics on the fastest timescales. The instrument was built by a consortium involving the Universities of Sheffield (Vik Dhillon), Warwick (Tom Marsh) and the UK Astronomy Technology Centre, Edinburgh. It saw first light on the 4.2-m William Herschel Telescope (WHT) on La Palma in 2002. The large quantity of observing time awarded to ULTRACAM (totalling one year of nights over the last decade) on some of the world's largest telescopes is testament to the competitiveness of the science performed with the instrument.

Probing Nuclear Activity Versus Star Formation Using Near-Infrared Multi-Object Spectroscopy

jma@ing.iac.es (Javier Mendez) — Mon, 4 Feb 2013 11:00:00 GMT

The role of active galactic nuclei (AGN) in the formation and evolution of galaxies is still not well established. Some authors claim that AGN are key in quenching star formation in their host galaxies through so-called AGN feedback, which has been invoked to explain the well-established correlations between supermassive-black-hole (SMBH) mass and host-galaxy properties. In order to understand the importance of AGN feedback in the star-formation histories of galaxies, it is necessary to study how the star formation rate (SFR) in active galaxies evolves with redshift.

SAURON Team Gets the 2013 Group Achievement Award of the Royal Astronomical Society

jma@ing.iac.es (Javier Mendez) — Fri, 25 Jan 2013 09:00:00 GMT

First Evidence of the Relation Between Jets in Planetary Nebulae and Mass Transfer and Accretion in Close Binaries

jma@ing.iac.es (Javier Mendez) — Wed, 12 Dec 2012 12:00:00 GMT

The formation of asymmetric structures such as rings and jets in planetary nebulae (PNe) has been a matter of debate for a long time. The most popular hypothesis is that these features are produced in interacting binaries. Using data obtained with ACAM imager and spectrograph on the William Herschel Telescope, for the first time astronomers have been able to reliably relate jet ejections to mass transfer and accretion in a close binary in a planetary nebula.

A 3D View of the Remnant of Nova Persei 1901

jma@ing.iac.es (Javier Mendez) — Tue, 11 Dec 2012 10:00:00 GMT

GK Per (Nova Persei 1901) nova remnant is the result of a remarkable nearby nova exploded in 1901 which reached the brightness of the star Vega at its maximum. It was the first object around which, superluminal light echoes where observed. The actual ejecta of the outburst became visible 15 years later in 1916. Ever since, the ejecta has been monitored in several wavelengths in narrow- and broad-band filters. This study shows that the nova ejecta is a thick knotty shell in which knots expand with a significant range of velocities. A movie shows the evolution of the remnant from 1953 to 2011 using data mainly from the INT/WFC and INT/IDS.

Astronomy Advisory Panel Draft Report - Community Input Sought

balcells@ing.iac.es (Marc Balcells) — Wed, 24 Oct 2012 20:00:00 GMT

STFC recently circulated the Astronomy Advisory Panel's draft report for the upcoming STFC programmatic review. STFC requests feedback on this draft via the linked web form. Please note the deadline, NOON OF THURSDAY 25 OCTOBER. With this late reminder, I strongly encourage all ING users who have not yet responded to provide their input via the web form. ING welcomes the report's consistent emphasis on the desirability of maintaining diversity of facilities in the run-up to E-ELT and SKA, and on the importance of future UK access to a powerful MOS.

However, current and future ING users may be concerned that two critical issues receive little attention in this report. Firstly, there is almost no discussion of the requirement to maintain Northern-hemisphere access for UK optical observers. Secondly, no mention is made of a clear path that exists for providing UK users with Northern MOS access (highlighted on p16 as being required for 3 out of 7 science areas), namely via the planned WEAVE spectrograph on the WHT (2-deg field, 1000 fibres).

If the report does not reflect your views about these issues, or others, we encourage you to provide feedback on the above link. We are very grateful for the support you have given in the past to the continued involvement of the UK in the ING. Your contribution is very important for the success of the process.

Many thanks in advance,

Marc Balcells
Director ING

The Cold Veil of the Milky Way Stellar Halo

jma@ing.iac.es (Javier Mendez) — Fri, 21 Sep 2012 18:00:00 GMT

Astronomers at the Institute of Astronomy in Cambridge (UK) have reported the discovery of a "cold veil" of halo stars in the very outskirts of the Milky Way. They obtained the radial velocities of a sample of distant halo stars located from 80 to 150 kiloparsecs from the center of our Galaxy using the ISIS spectrograph on the William Herschel Telescope (WHT), among others. The two most distant stars in this sample are Carbon stars observed with WHT/ISIS, and to date, they are the most distant field Galactic halo stars with radial-velocity measurements.

Quantum Teleportation Experiment Sets a New Record

jma@ing.iac.es (Javier Mendez) — Thu, 20 Sep 2012 15:00:00 GMT

Physicists at the University of Vienna and the Austrian Academy of Sciences have successfully transmitted quantum states between La Palma (from the Jacobus Kapteyn Telescope) and Tenerife, over a record distance of 143 km. This experiment provides the basis for a worldwide information network, in which quantum mechanical effects enable the exchange of messages with greater security, and allow certain calculations to be performed more efficiently than with conventional technologies. In such a future 'quantum internet', quantum teleportation will be a key protocol for the transmission of information between quantum computers.

The Transiting Earth

jma@ing.iac.es (Javier Mendez) — Wed, 12 Sep 2012 11:00:00 GMT

From spectra collected during the August 2008 lunar eclipse, astronomers have been able to investigate the in-transit signature of the Earth-Sun system as would be observed from outside the solar system. They found that the refraction of sunlight as it passes through a planetary atmosphere similar to the Earth's contributes prominently to the in-transit transmission spectrum. This research has important implications for future attempts to characterise the atmospheres of Earth-like extrasolar planets, especially those in similar long-period orbits.

The Nature of the Driving Source of the HH30 Jet/Counterjet System

jma@ing.iac.es (Javier Mendez) — Mon, 13 Aug 2012 14:00:00 GMT

The Herbig-Haro object 30 (HH30) is located in the L1551 dark cloud, at a distance of about 140 parsec, in the Taurus star-forming region. HH30 is considered a prototypical jet-disk system driven by a young stellar object (YSO). The impressive jet/counterjet structure extends several arcminutes in both directions from the exciting source, and shows an undulating morphology in the narrow-band [SII] images. Astronomers using ACAM at the William Herschel Telescope have been able to obtain a deep image of the HH30 field and have found an interesting explanation for the jet/counterjet system.

The Kepler-INT Survey

Masgomas-1: A Very Massive Stellar Cluster

jma@ing.iac.es (Javier Mendez) — Wed, 23 May 2012 16:00:00 GMT

A group of astronomers from IAC and CEFCA have reported the discovery of a massive stellar cluster in the Milky Way. The discovery is part of the MASGOMAS project (MAssive Stars in Galactic Obscured MAssive clusterS), a systematic search for massive galactic stellar clusters. The massive nature of the cluster has been confirmed using LIRIS imaging, and long-slit and multi-object spectroscopy, on the William Herschel Telescope (WHT).

The World's Greatest Telescopes

jma@ing.iac.es (Javier Mendez) — Fri, 18 May 2012 11:00:00 GMT

The William Herschel Telescope takes pride of place on the front cover of Astronomy magazine's special summer 2012 issue. This issue is a picture-packed guided tour of the world's major observatories, highlighting the beauty of the locations as much as the scientific achievements. It includes an article about the Roque de los Muchachos Observatory on La Palma, written by ING staff Chris Benn, Javier Mendez and Marc Balcells.

NGC 2359 Nebula

jma@ing.iac.es (Javier Mendez) — Tue, 08 May 2012 10:00:00 GMT

This is an image of NGC 2359, better known as the Thor's Helmet nebula, obtained using the Wide-Field Camera on the Isaac Newton Telescope. NGC 2359 is actually more like an interstellar bubble, blown as a fast wind from the bright, massive star near the bubble's center sweeps through a surrounding molecular cloud. The central star is an extremely hot giant Wolf-Rayet star thought to be in a brief, pre-supernova stage of evolution.

Astronomy Field Trip by University of Sheffield Students

jma@ing.iac.es (Javier Mendez) — Fri, 27 Apr 2012 17:00:00 GMT

A group of 8 Sheffield MPhys students visited La Palma for one week to undertake their third-year astronomy project using pt5m, the Durham-Sheffield 0.5m robotic telescope on the roof of the WHT. The trip, which was led by Professor Vik Dhillon, was a great success and will hopefully now be an annual fixture in the Sheffield Astrophysics MPhys degree programme.

Under the Dark Halo Old Galaxies Have Many More Stars

jma@ing.iac.es (Javier Mendez) — Thu, 26 Apr 2012 12:00:00 GMT

Astronomers from the Atlas3D team, using the SAURON integral-field spectrograph on the William Herschel Telescope, have found that some of the oldest galaxies in the Universe have three times as much stellar mass, and as many more stars, than all current models of galaxy evolution predict. This result means that the models, which assumed for decades that the light we observe from a galaxy can be used to infer its stellar mass, will have to be revised. A report of the research is published in Nature on 26 April 2012.

Riding the Wake of a Merging Galaxy Cluster

jma@ing.iac.es (Javier Mendez) — Sat, 10 Mar 2012 20:00:00 GMT

Observations using the OASIS integral field spectrograph on the William Herschel Telescope have revealed a long, thin plume of ionised gas stretching out from the brightest cluster galaxy (BCG) of Abell 2146 (z=0.243) (Canning et al. 2012). Extended optical emission-line nebulae are not uncommon in the cores of clusters, but the discovery of this particular structure is unexpected, as the host cluster is in the throes of a major merger event.

The ING Telescopes Contribute to the 2011 Nobel Prize in Physics

jma@ing.iac.es (Javier Mendez) — Tue, 4 Oct 2011 21:00:00 GMT

The Isaac Newton Group of Telescopes (ING) contributed data to the research which led to the award of the 2011 Nobel Prize in Physics to Professor Saul Perlmutter of UC-Berkeley. Using wide-field imaging techniques implemented on the Isaac Newton Telescope (INT) in the early nineties, and subsequent imaging and spectroscopy using the William Herschel Telescope (WHT), among others, the Supernova Cosmology Project team led by Perlmutter discovered that the expansion of the Universe, long-believed to be decelerating due to the effects of gravitational attraction, was in fact accelerating, that is, galaxies are receding from one another faster now than they were billions of years ago. This result provided the foundation for the current, widely-accepted model of the Universe, in which the dynamics are dominated by what is called dark energy.

The ATLAS 3D Project: Replacing the Handle of Hubbles Tuning Fork

jma@ing.iac.es (Javier Mendez) — Mon, 20 Jun 2011 16:00:00 GMT

Since Edwin Hubble introduced his famous tuning fork diagram more than 70 years ago, spiral galaxies and early-type galaxies have been regarded as being two distinct families. A known issue of Hubble's classification, however, is that it mostly relies on optical images, from which it is nearly impossible to recognize thin face-on disks of stars from much rounder edge-on spheroids. For this reason the fraction of disks-like systems hidden in the early-type category has been a matter of debate for decades. Using SAURON integral-field spectrograph at the William Herschel Telescope, astronomers of the ATLAS 3D collaboration were able to derive maps of the stellar motions for 260 galaxies. For the first time, it was found that the overwhelming majority of the early-type galaxies in the nearby Universe does not consist of roundish spheroidal objects, but instead has disks and mostly resembles spiral galaxies with the gas and dust removed. Only a tiny fraction of the early-type galaxies, the "slow rotators", are genuine spheroids.

Discovery of a New Class of Supernovae

Wide-Field Multi-Object Spectrograph WEAVE Proposed for WHT Prime Focus

balcells@ing.iac.es (Marc Balcells) — Sun, 29 May 2011 18:00:00 GMT

ING is establishing a European consortium to develop a spectrograph, WEAVE, for the prime focus of the William Herschel Telescope. WEAVE will be able to take spectra of up to 1000 objects simultaneously, within a 2-deg field of view. First light is envisioned in 2016.

ING Joins Efforts with GTC to Discover a Galactic Black Hole

jma@ing.iac.es (Javier Mendez) — Mon, 25 Apr 2011 10:00:00 GMT

XTE J1859+226 is a transient X-ray binary discovered in 1999 by the X-ray satellite RXTE. This type of binary system stays in quiescence for most of its life; however, from time-to-time the system can show an outburst at all wavelengths which can subsequently be detected by X-ray satellites. By combining the data taken using the INT and the WHT in 2000 with the photometry taken in 2008 with NOT, WHT and spectra from GTC, a lower limit to the mass of the black hole was set to 5.42 solar masses.

Galaxy Zoo Supernovae and the WHT

jma@ing.iac.es (Javier Mendez) — Mon, 11 Apr 2011 17:00:00 GMT

Galaxy Zoo Supernovae (GZS) is a proof-of-concept project which uses members of the public to identify supernova candidates from the latest generation of wide-field imaging transient surveys. GZS was first tested on two specific occasions supporting Palomar Transient Factory (PTF) spectroscopic follow-up observations at the William Herschel Telescope, in 2009 August and October. 16 of 20 candidates were observed by the WHT; 15 were confirmed as SNe, with one cataclysmic variable. Since 2010 April, GZS has been running full-time on PTF candidates and by 2010 July 15 had classified around 13,900 SN candidates at the rate of several hundred candidates per observing night. SGZ team members continue to use the WHT to confirm and follow up the SN candidates being discovered.

CANARY: First On-Sky Demonstration of Multi-Object Adaptive Optics

jma@ing.iac.es (Javier Mendez) — Wed, 29 Dec 2010 13:00:00 GMT

A Franco-British team has demonstrated for the first time on-sky the feasibility of so-called Multi-Object Adaptive Optics (MOAO). MOAO provides the high spatial resolution delivered by current adaptive-optics systems, but over a much larger field of view, allowing many objects to be observed simultaneously. The demonstration was made with the purpose-built CANARY instrument installed at the Nasmyth focus of the William Herschel Telescope on La Palma. Analysis of the first results obtained in September 2010 shows that CANARY delivered the expected performance the first time it was used - a spectacular success.

Electron-multiplying CCDs at ING

jma@ing.iac.es (Javier Mendez) — Wed, 27 Oct 2010 15:00:00 GMT

Conventional CCD detectors have two major disadvantages: they are slow to read out and they suffer from read noise. These problems combine to make high-speed spectroscopy of faint targets the most demanding of astronomical observations. It is possible to overcome these weaknesses by using electron-multiplying CCDs (EMCCDs). EMCCDs are conventional frame-transfer CCDs, but with an extended serial register containing high voltage electrodes. The recently released ING technical note no. 132 summarises the research and the implementation of EMCCDs at ING.
