High-Redshift SDSS Quasars with Weak Emission Lines (2009)
Diamond-Stanic, Aleksandar M., Fan, Xiaohui, Brandt, W. N., Shemmer, Ohad, Strauss, Michael A., Anderson, Scott F., ...
We identify a sample of 74 high-redshift quasars (z>3) with weak emission lines from the Fifth Data Release of the Sloan Digital Sky Survey and present infrared, optical, and radio observations of a...
X-Ray Insights Into the Physics of Mini-BAL Quasar Outflows (2009)
Gibson, Robert R., Brandt, W. N., Gallagher, S. C., Schneider, Donald P.
We examine the UV and X-ray properties of 256 radio-quiet SDSS quasars (QSOs) observed in X-rays with Chandra and/or XMM-Newton in order to study the relationship between QSOs with broad CIV...
A Catalog of Broad Absorption Line Quasars in Sloan Digital Sky Survey Data Release 5 (2008)
Gibson, Robert R., Jiang, Linhua, Brandt, W. N., Hall, Patrick B., Shen, Yue, Wu, Jianfeng, ...
We present a catalog of 5039 broad absorption line (BAL) quasars (QSOs) in the Sloan Digital Sky Survey (SDSS) Data Release 5 (DR5) QSO catalog that have absorption troughs covering a continuous...
Gibson, Robert R., Brandt, W. N., Schneider, Donald P.
We analyze archived Chandra and XMM-Newton X-ray observations of 536 Sloan Digital Sky Survey (SDSS) Data Release 5 (DR5) quasars (QSOs) at 1.7
Quasar Broad Absorption Line Variability on Multi-Year Time Scales (2007)
Gibson, Robert R., Brandt, W. N., Schneider, Donald P., Gallagher, S. C.
We use quantitative metrics to characterize the variation of CIV 1549 A broad absorption lines (BALs) over 3--6 (rest-frame) years in a sample of 13 quasars at 1.7
