Broad Absorption Line Variability in Radio-Loud Quasars
C. A. Welling, B. P. Miller, W. N. Brandt +2
We investigate C IV broad absorption line (BAL) variability within a sample of 46 radio-loud quasars (RLQs), selected from SDSS/FIRST data to include both core-dominated (39) and l…
Variability in Quasar Broad Absorption Line Outflows
Daniel M. Capellupo, Fred Hamann, Joseph C. Shields +3
Broad absorption lines (BALs) in quasar spectra identify high velocity outflows that likely exist in all quasars and could play a major role in feedback to galaxy evolution. Studyi…
Narrow UV Absorption Line Outflows from Quasars
Fred Hamann, Leah Simon, Paola Rodriguez Hidalgo +1
Narrow absorption line (NAL) outflows are an important yet poorly understood part of the quasar outflow phenomenon. We discuss one particular NAL outflow that has high speeds, time…
Variability of Mini-BAL and BAL Outflows in Quasars
Paola Rodriguez Hidalgo, Fred Hamann, Michael Eracleous +3
We report the results of several programs to study the variability of high-velocity (up to 0.2c) mini-"broad absorption lines" (mini-BALs) and BALs in quasar spectra, and thus to b…
