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).

(z=3.87) compared to the ultraluminous galaxies IRAS F10214+4724 (z=2.286),
SMM 02399-0136 (z=2.8), and H1413+117 (z=2.558) (extracted from M. J. Irwin

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).
