The Sloan Digital Sky Survey Quasar Catalog IV. Fifth Data Release
Donald P. Schneider, Patrick B. Hall, Gordon T. Richards +41
We present the fourth edition of the Sloan Digital Sky Survey (SDSS) Quasar Catalog. The catalog contains 77,429 objects; this is an increase of over 30,000 entries since the previ…
Clustering of High Redshift () Quasars from the Sloan Digital Sky Survey
Yue Shen, Michael A. Strauss, Masamune Oguri +13
(Abridged) We study the two-point correlation function of a uniformly selected sample of 4,426 luminous optical quasars with redshift selected over 4041 deg…
Statistical Properties of the GALEX/SDSS matched source catalogs, and classification of the UV sources
Luciana Bianchi, Lino Rodriguez-Merino, Maurice Viton +30
We use the Galaxy Evolution Explorer (GALEX) Medium and All-Sky-Imaging Survey (MIS & AIS) data from the first public data release (GR1), matched to the Sloan Digital Sky Survey (S…
The SDSS Quasar Survey: Quasar Luminosity Function from Data Release Three
Gordon T. Richards, Michael A. Strauss, Xiaohui Fan +19
We determine the number counts and z=0-5 luminosity function for a well-defined, homogeneous sample of quasars from the Sloan Digital Sky Survey (SDSS). We conservatively define th…
Broad Emission Line Shifts in Quasars: An Orientation Measure for Radio-Quiet Quasars?
Gordon T. Richards, Daniel E. Vanden Berk, Timothy A. Reichard +5
Using a sample of 3814 quasars from the Sloan Digital Sky Survey, we confirm that high-ionization, broad, emission lines such as CIV are significantly blueshifted with respect to l…
Stellar Masses and Star Formation Histories for 10^5 Galaxies from the Sloan Digital Sky Survey
Guinevere Kauffmann, Timothy M. Heckman, Simon D. M. White +19
We develop a new method to constrain the star formation histories, dust attenuation and stellar masses of galaxies. It is based on two stellar absorption line indices, the 4000 Ang…
