The 2dF���SDSS LRG and QSO survey: the QSO luminosity function at 0.4 &lt;<i>z</i>&lt; 2.6

Abstract

We present the quasi-stellar object (QSO) luminosity function (LF) of the completed 2dF-SDSS LRG and QSO (2SLAQ) survey, based on QSOs photometrically selected from Sloan Digital Sky Survey (SDSS) imaging data and then observed spectroscopically using the 2dF instrument on the Anglo-Australian Telescope. We analyse 10 637 QSOs in the redshift range 0.4 < z < 2.6 to a g-band flux limit of 21.85 (extinction-corrected) and an absolute continuum magnitude of M g (z = 2) < -21.5. This sample covers an area of 191.9 deg 2 .
