Photometric selection of QSO candidates from galex sources

We present a catalog of 36,120 QSO candidates from the Galaxy Evolution Explorer (GALEX) Release Two (GR2) UV catalog and the USNO-A2.0 optical catalog. The selection criteria are established using known quasars from the Sloan Digital Sky Survey (SDSS). The SDSS sample is then used to assign individual probabilities to our GALEX USNO candidates. The mean probability is similar to 50% and would rise to similar to 65% if better morphological information than that from USNO were available to eliminate galaxies. The sample is similar to 40% complete for i <= 19.1. Candidates are cross identified in 2MASS, FIRST, SDSS, and the XMM-Newton Slewing Survey (XMMSL1), whenever such counterparts exist. The present catalog covers the 8000 deg(2) of GR2 lying above vertical bar b vertical bar = 25 degrees, but can be extended to all 24,000 deg(2) that satisfy this criterion as new GALEX data become available.
