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 effect of nuclear gas distribution on the mass determination of supermassive black holes
J. E. Mejía-Restrepo, P. Lira, H. Netzer +2
Supermassive black holes reside in the nuclei of most galaxies. Accurately determining their mass is key to understand how the population evolves over time and how the black holes…
A Comparison of Two Methods for Estimating Black Hole Spin in Active Galactic Nuclei
Daniel M. Capellupo, Gaylor Wafflard-Fernandez, Daryl Haggard
Angular momentum, or spin, is a fundamental property of black holes (BHs), yet it is much more difficult to estimate than mass or accretion rate (for actively accreting systems). I…
Active galactic nuclei at z ~ 1.5: III. Accretion discs and black hole spin
Daniel M. Capellupo, Hagai Netzer, Paulina Lira +2
This is the third paper in a series describing the spectroscopic properties of a sample of 39 AGN at , selected to cover a large range in black hole mass () and…
Active galactic nuclei at z~1.5: II. Black Hole Mass estimation by means of broad emission lines
Julián E. Mejía-Restrepo, Benny Trakhtenbrot, Paulina Lira +2
This is the second in a series of papers aiming to test how the mass (), accretion rate () and spin () of super massive black holes (SMBHs) determine th…
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…
