Monitoring Quasar Colour Variability in Stripe 82
Jesse A. Rogerson, Patrick B. Hall, Chelsea MacLeod +1
Broad Absorption Line (BAL) trough variability is predominantly due to cloud motion transverse to our line of sight. The rate at which the variability occurs indicates the velocity…
Investigating MgII Absorption in Paired Quasar Sight-Lines
Jesse A. Rogerson, Patrick B. Hall
We test whether the Tinker & Chen model of MgII absorption due to the gaseous halo around a galaxy can reproduce absorption in quasar pairs (both lensed and physical) and lensed tr…
Chandra X-Ray Observations of Two Unusual BAL Quasars
Jesse A. Rogerson, Patrick B. Hall, Stephanie A. Snedden +2
We report sensitive Chandra X-ray non-detections of two unusual, luminous Iron Low-Ionization Broad Absorption Line Quasars (FeLoBALs). The observations do detect a non-BAL, wide-b…
