dc.description.abstract | We describe further results of a program aimed to yield ∼104 fully characterized optical
identifications of ROSAT X-ray sources. Our program employs X-ray data from the ROSAT
All-Sky Survey (RASS), and both optical imaging and spectroscopic data from the Sloan Digital
Sky Survey (SDSS). RASS/SDSS data from 5740 deg2 of sky spectroscopically covered in SDSS
Data Release 5 (DR5) provide an expanded catalog of 7000 confirmed quasars and other AGN
that are probable RASS identifications. Again in our expanded catalog, the identifications as
X-ray sources are statistically secure, with only a few percent of the SDSS AGN likely to be
randomly superposed on unrelated RASS X-ray sources. Most identifications continue to be
quasars and Seyfert 1s with 15 < m < 21 and 0.01 < z < 4; but the total sample size has
grown to include very substantial numbers of even quite rare AGN, e.g., now including several
hundreds of candidate X-ray emitting BL Lacs and narrow-line Seyfert 1 galaxies. In addition
to exploring rare subpopulations, such a large total sample may be useful when considering
correlations between the X-ray and the optical, and may also serve as a resource list from which
to select the “best” object (e.g., X-ray brightest AGN of a certain subclass, at a preferred redshift
or luminosity) for follow-on X-ray spectral or alternate detailed studies. | en_US |
