The SDSS View of the Palomar-Green Bright Quasar Survey
Sebastian Jester, Donald P. Schneider, Gordon T. Richards +12
We investigate the extent to which the Palomar-Green (PG) Bright Quasar Survey (BQS) is complete and representative of the general quasar population by comparing with imaging and s…
The Lyman-alpha Forest Power Spectrum from the Sloan Digital Sky Survey
Patrick McDonald, Uros Seljak, Scott Burles +8
We measure the power spectrum, P_F(k,z), of the transmitted flux in the Ly-alpha forest using 3035 high redshift quasar spectra from the Sloan Digital Sky Survey. This sample is al…
Observations and Theoretical Implications of the Large Separation Lensed Quasar SDSS J1004+4112
M. Oguri, N. Inada, C. R. Keeton +25
We study the recently discovered gravitational lens SDSS J1004+4112, the first quasar lensed by a cluster of galaxies. It consists of four images with a maximum separation of 14.62…
Angular Clustering with Photometric Redshifts in the Sloan Digital Sky Survey: Bimodality in the Clustering Properties of Galaxies
Tamas Budavari, Andrew J. Connolly, Alexander S. Szalay +18
Understanding the clustering of galaxies has long been a goal of modern observational cosmology. Utilizing our photometric redshift technique a volume limited sample containing mor…
