APM 08279+5255: An Ultraluminous Broad Absorption Line Quasar at a Redshift z = 3.87
@article{Irwin1998APM0A, title={APM 08279+5255: An Ultraluminous Broad Absorption Line Quasar at a Redshift z = 3.87}, author={Michael J. Irwin and Rodrigo A. Ibata and Geraint F. Lewis Edward J. Totten}, journal={The Astrophysical Journal}, year={1998}, volume={505}, pages={529-535} }
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…
