We report on the discovery of a highly luminous, broad absorption line quasar at a redshift of z = 3.87, which is positionally coincident, within 1'', with the IRAS Faint Source Catalog source F08279+5255. A chance alignment of the quasar and the IRAS source is extremely unlikely, and we argue that the optical and far-infrared flux are different manifestations of the same object. With an R-band magnitude of 15.2 and an IRAS 60 μm flux of 0.51 Jy, APM 08279+5255 is (apparently) easily the most…

We present a spatially resolved imaging analysis of a three-component gravitationally lensed quasar at z = 3.91, APM 08279+5255, in the L0and M 0-bands, and a narrow band centered at 3.05 m using the
Photometric Monitoring of the Gravitationally Lensed Ultraluminous Broad Absorption Line Quasar APM 08279+5255
We report on 1 year of photometric monitoring of the ultraluminous broad absorption line quasar APM 08279+5255. The temporal sampling reveals that this gravitationally lensed system has brightened by
Heavily reddened quasars at z ∼ 2 in the UKIDSS Large Area Survey: a transitional phase in AGN evolution
We present a new sample of purely near-infrared-selected KVega 2.5] quasar candidates at z ∼ 2 from ≃900 deg2 of data in the UKIDSS Large Area Survey (LAS). Five of these are spectroscopically
A multi-epoch spectroscopic study of the BAL quasar APM 08279+5255: I. C IV absorption variability
Broad Absorption Lines indicate gas outflows with velocities from thousands km/s to about 0.2 the speed of light, which may be present in all quasars and may play a major role in the evolution of the

Molecular gas and dust around a radio-quiet quasar at redshift 4.69
TLDR
The detection of carbon monoxide confirms the presence of a large mass of molecular gas in one of the most distant galaxies known, and shows that conditions conducive to huge bursts of star formation existed in the very early Universe.
