Press Photo ING PP1/98b  Optical Spectra of APM 08279+5255 taken with the 2.5m Isaac Newton Telescope. Features typical of high-redshift quasars, namely, strong N V and C IV emission lines, are clearly visible. The emission lines are seen to possess broad absorption troughs consistent with high-velocity bulk outflows associated with the quasar (extracted from M. J. Irwin et al., ApJ, 505, 529).  [tiff, 1.5M]

The Isaac Newton Group of telescopes (ING) consists of the 4.2m William Herschel Telescope, the 2.5m Isaac Newton Telescope and the 1.0m Jacobus Kapteyn Telescope. The ING is owned and operated jointly by the UK's Particle Physics and Astronomy Research Council (PPARC) and the Netherlands' Nederlandse Organisatie voor Wetenschappelijk Onderzoek (NWO). The telescopes are located in the Spanish Observatorio del Roque de Los Muchachos on La Palma which belongs to the Instituto de Astrofísica de Canarias (IAC).
