Quasar outflow energetics from broad absorption line variability
S. M. McGraw, J. C. Shields, F. W. Hamann +2
Quasar outflows have long been recognized as potential contributors to the co-evolution between supermassive black holes (SMBHs) and their host galaxies. The role of outflows in AG…
The Time-Domain Spectroscopic Survey: Target Selection for Repeat Spectroscopy
Chelsea L. MacLeod, Paul J. Green, Scott F. Anderson +35
As astronomers increasingly exploit the information available in the time domain, spectroscopic variability in particular opens broad new channels of investigation. Here we describ…
Broad absorption line disappearance and emergence using multiple-epoch spectroscopy from the Sloan Digital Sky Survey
S. M. McGraw, W. N. Brandt, C. J. Grier +8
We investigate broad absorption line (BAL) disappearance and emergence using a 470 BAL-quasar sample over < 0.10-5.25 rest-frame years with at least three spectroscopic epochs for…
The Physics and Physical Properties of Quasar Outflows
Fred Hamann, Daniel Capellupo, George Chartas +5
We describe two studies designed to characterize the total column densities, kinetic energies, and acceleration physics of broad absorption line (BAL) outflows in quasars. The firs…
