A Catalog of Broad Absorption Line Quasars in Sloan Digital Sky Survey Data Release 5
Robert R. Gibson, Linhua Jiang, W. N. Brandt +9
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 coverin…
Are Optically-Selected Quasars Universally X-Ray Luminous? X-Ray/UV Relations in Sloan Digital Sky Survey Quasars
Robert R. Gibson, W. N. Brandt, Donald P. Schneider
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 <= z <= 2.7 in order to characterize…
Quasar Broad Absorption Line Variability on Multi-Year Time Scales
Robert R. Gibson, W. N. Brandt, Donald P. Schneider +1
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 <= z <= 2.8 and…
A Chandra HETGS Spectral Study of the Iron K Bandpass in MCG-6-30-15: A Narrow View of the Broad Iron Line
A. J. Young, J. C. Lee, A. C. Fabian +3
We present a high resolution X-ray spectrum of the iron K bandpass in MCG-6-30-15 based on a 522 ksec observation with Chandra's High Energy Transmission Grating Spectrometer. The…
