Constraints on Quasar Continuum, BELR, and BALR Physics from SDSS Composite Spectra
Gordon T. Richards, Patrick B. Hall, Timothy A. Reichard +3
We review recent results on quasars from the SDSS as they relate to our understanding of the UV/optical continuum, the broad emission line region, and the broad absorption line reg…
Luminosity and Redshift Dependence of Quasar Spectral Properties
D. E. Vanden Berk, C. -Y. Yip, A. J. Connolly +2
Using a large sample of quasar spectra from the SDSS, we examine the composite spectral trends of quasars as functions of both redshift and luminosity, independently of one another…
Continuum and Emission-Line Properties of Broad Absorption Line Quasars
Timothy A. Reichard, Gordon T. Richards, Patrick B. Hall +6
We investigate the continuum and emission-line properties of 224 broad absorption line quasars (BALQSOs) with 0.9<z<4.4 drawn from the Sloan Digital Sky Survey (SDSS) Early Data Re…
The Sloan Digital Sky Survey Quasar Catalog II. First Data Release
Donald P. Schneider, Xiaohui Fan, Patrick B. Hall +13
We present the second edition of the Sloan Digital Sky Survey (SDSS) Quasar Catalog. The catalog consists of 16713 objects in the SDSS First Data Release (DR1) that have luminositi…
Damped Lyman Alpha Gas Metallicities at Redshifts z=0.9-2.0 from SDSS Spectra
Daniel B. Nestor, Sandhya M. Rao, David A. Turnshek +1
Using Sloan Digital Sky Survey (SDSS) early data release spectra, we have identified 370 MgII absorption systems with MgII 2796 rest equivalent widths >= 1A and redshifts z=0.9-2.2…
An Initial Survey of White Dwarfs in the Sloan Digital Sky Survey
H. C. Harris, J. Liebert, S. J. Kleinman +35
An initial assessment is made of white dwarf and hot subdwarf stars observed in the Sloan Digital Sky Survey. In a small area of sky (190 square degrees), observed much like the fu…
