The Sloan Digital Sky Survey Quasar Catalog I. Early Data Release
Donald P. Schneider, Gordon T. Richards, Xiaohui Fan +9
We present the first edition of the Sloan Digital Sky Survey (SDSS) Quasar Catalog. The catalog consists of the 3814 objects (3000 discovered by the SDSS) in the initial SDSS publi…
The UCSD HIRES/KeckI Damped Lya Abundance Database: I. The Data
Jason X. Prochaska, Arthur M. Wolfe, David Tytler +6
We present new chemical abundance measurements of 16 damped Lya systems at z>1.5 and update our previous abundance analyses. The entire database presented here was derived from HIR…
Early-type galaxies in the SDSS
M. Bernardi, R. K. Sheth, J. Annis +28
A sample of nearly 9000 early-type galaxies, in the redshift range 0.01<z<0.3, was selected from the Sloan Digital Sky Survey using morphological and spectral criteria. The sample…
Nucleosynthesis Clocks and the Age of the Galaxy
J. W. Truran, S. Burles, J. J. Cowan +1
Nucleocosmochronology involves the use of the abundances of radioactive nuclear species and their radiogenic decay daughters to establish the finite age of the elements and the tim…
Spectroscopic Target Selection for the Sloan Digital Sky Survey: The Luminous Red Galaxy Sample
D. J. Eisenstein, J. Annis, J. E. Gunn +25
We describe the target selection and resulting properties of a spectroscopic sample of luminous, red galaxies (LRG) from the imaging data of the Sloan Digital Sky Survey (SDSS). Th…
Photometric Redshifts of Quasars
Gordon T. Richards, Michael A. Weinstein, Donald P. Schneider +3
We demonstrate that the design of the Sloan Digital Sky Survey (SDSS) filter system and the quality of the SDSS imaging data are sufficient for determining accurate and precise pho…
