FeLoBAL Outflow Variability Constraints from Multi-Year Observations
Sean M. McGraw, Joseph C. Shields, Frederick W. Hamann +3
The physical properties and dynamical behavior of Broad Absorption Line (BAL) outflows are crucial themes in understanding the connections between galactic centers and their hosts.…
Extreme-Velocity Quasar Outflows and the Role of X-ray Shielding
Fred Hamann, George Chartas, Sean McGraw +5
Quasar accretion disk winds observed via broad absorption lines (BALs) in the UV produce strong continuous absorption in X-rays. The X-ray absorber is believed to serve critically…
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…
