Constraining the Evolution of the Ionizing Background and the Epoch of Reionization with z ~ 6 Quasars II: A Sample of 19 Quasars
Xiaohui Fan, Michael A. Strauss, Robert H. Becker +7
We study the evolution of the ionization state of the IGM at the end of the reionization epoch using spectra of a sample of nineteen quasars at 5.74<z<6.42 discovered in the SDSS.…
SDSSJ103913.70+533029.7: A Super Star Cluster in the Outskirts of a Galaxy Merger
G. R. Knapp, C. A. Tremonti, C. M. Rockosi
We describe the serendipitous discovery in the spectroscopic data of the Sloan Digital Sky Survey of a star-like object, SDSSJ103913.70+533029.7, at a heliocentric radial velocity…
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…
Detection of Cosmic Magnification with the Sloan Digital Sky Survey
Ryan Scranton, Brice Menard, Gordon T. Richards +15
We present an 8 sigma detection of cosmic magnification measured by the variation of quasar density due to gravitational lensing by foreground large scale structure. To make this m…
The Sloan Digital Sky Survey Quasar Catalog III. Third Data Release
D. P. Schneider, P. B. Hall, G. T. Richards +50
We present the third edition of the Sloan Digital Sky Survey (SDSS) Quasar Catalog. The catalog consists of the 46,420 objects in the SDSS Third Data Release that have luminosities…
Detection of the Baryon Acoustic Peak in the Large-Scale Correlation Function of SDSS Luminous Red Galaxies
D. J. Eisenstein, I. Zehavi, D. W. Hogg +45
We present the large-scale correlation function measured from a spectroscopic sample of 46,748 luminous red galaxies from the Sloan Digital Sky Survey. The survey region covers 0.7…
