The Seventh Data Release of the Sloan Digital Sky Survey
K. Abazajian
This paper describes the Seventh Data Release of the Sloan Digital Sky Survey (SDSS), marking the completion of the original goals of the SDSS and the end of the phase known as SDS…
On the variability of quasars: a link between Eddington ratio and optical variability?
B. C. Wilhite, R. J. Brunner, C. J. Grier +2
Repeat scans by the Sloan Digital Sky Survey (SDSS) of a 278 square degree stripe along the Celestial equator have yielded an average of over 10 observations each for nearly 8,000…
The Effect of Variability on the Estimation of Quasar Black Hole Masses
B. C. Wilhite, R. J. Brunner, D. P. Schneider +1
We investigate the time-dependent variations of ultraviolet (UV) black hole mass estimates of quasars in the Sloan Digital Sky Survey (SDSS). From SDSS spectra of 615 high-redshift…
The Fifth Data Release of the Sloan Digital Sky Survey
Jennifer K. Adelman-McCarthy
This paper describes the Fifth Data Release (DR5) of the Sloan Digital Sky Survey (SDSS). DR5 includes all survey quality data taken through June 2005 and represents the completion…
Broad Absorption Line Variability in Repeat Quasar Observations from the Sloan Digital Sky Survey
Britt F. Lundgren, Brian C. Wilhite, Robert J. Brunner +5
We present a time-variability analysis of 29 broad absorption line quasars (BALQSOs) observed in two epochs by the Sloan Digital Sky Survey (SDSS). These spectra are selected from…
A Synoptic, Multiwavelength Analysis of a Large Quasar Sample
Adam W. Rengstorf, Robert J. Brunner, Brian C. Wilhite
We present variability and multi-wavelength photometric information for the 933 known quasars in the QUEST Variability Survey. These quasars are grouped into variable and non-varia…
