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…
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…
