High-Redshift Quasars Found in Sloan Digital Sky Survey Commissioning Data VI. Sloan Digital Sky Survey Spectrograph Observations
Scott F. Anderson, Xiaohui Fan, Gordon T. Richards +4
We present results on over 100 high-redshift quasars found in the Sloan Digital Sky Survey (SDSS), using automated selection algorithms applied to SDSS imaging data and with spectr…
A New Very Cool White Dwarf Discovered by the Sloan Digital Sky Survey
H. C. Harris, B. M. S. Hansen, J. Liebert +33
Early data taken during commissioning of the SDSS have resulted in the discovery of a very cool white dwarf. It appears to have stronger collision induced absorption from molecular…
Colors of 2625 Quasars at 0<z<5 Measured in the Sloan Digital Sky Survey Photometric System
Gordon T. Richards, Xiaohui Fan, Donald P. Schneider +3
We present an empirical investigation of the colors of quasars in the Sloan Digital Sky Survey (SDSS) photometric system. The sample studied includes 2625 quasars with SDSS photome…
High-Redshift Quasars Found in Sloan Digital Sky Survey Commissioning Data V. Hobby-Eberly Telescope Observations
Donald P. Schneider, Xiaohui Fan, Michael A. Strauss +5
We report the discovery of 27 quasars with redshifts between 3.58 and 4.49. The objects were identified as high-redshift candidates based on their colors in Sloan Digital Sky Surve…
The Luminosity Function of Galaxies in SDSS Commissioning Data
SDSS Collaboration, M. R. Blanton
During commissioning observations, the Sloan Digital Sky Survey (SDSS) has produced one of the largest existing galaxy redshift samples selected from CCD images. Using 11,275 galax…
Optical and Infrared Colors of Stars Observed by 2MASS and SDSS
K. Finlator, Z. Ivezic, M. Strauss +4
We discuss optical and infrared photometric properties of stars matched in the Two Micron All Sky Survey (2MASS) and the Sloan Digital Sky Survey (SDSS) commissioning data for 50 d…
