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…
HST and Ground-Based Spectroscopy of Quasar Outflows: From Mini-BALs to BALs
E. A. Moravec, F. Hamann, D. M. Capellupo +3
Quasar outflows have been posited as a mechanism to couple super-massive black holes to evolution in their host galaxies. We use multi-epoch spectra from the Hubble Space Telescope…
