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…
On the Spectral Evolution of Cool, Helium-Atmosphere White Dwarfs: Detailed Spectroscopic and Photometric Analysis of DZ Stars
P. Dufour, P. Bergeron, James Liebert +6
We present a detailed analysis of a large spectroscopic and photometric sample of DZ white dwarfs based on our latest model atmosphere calculations. We revise the atmospheric param…
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…
Science Results Enabled by SDSS Astrometric Observations
Z. Ivezic, N. Bond, M. Juric +8
We discuss several results made possible by accurate SDSS astrometric measurements in a large sky area, with emphasis on asteroids and stellar proper motions obtained by comparing…
Near-Infrared Photometry and Spectroscopy of L and T Dwarfs: the Effects of Clouds, Gravity, and Effective Temperature
D. A. Golimowski, S. K. Leggett, M. S. Marley +2
We present new JHKL'M' photometry on the MKO system for a large sample of L and T dwarfs identified from SDSS and 2MASS and classified according to the scheme of Geballe et al. (20…
Cataclysmic Variables from SDSS III. The Third Year
Paula Szkody, Arne Henden, Oliver Fraser +17
This paper continues the series that identifies new cataclysmic variables found in the Sloan Digital Sky Survey. We present 36 cataclysmic variables and one possible symbiotic star…
