The host galaxies of FeLoBAL quasars at z0.9 are not dominated by recent major mergers
C. Villforth, H. Herbst, F. Hamann +4
Theoretical models have suggested an evolutionary model for quasars, in which most of luminous quasars are triggered by major mergers. It is also postulated that reddening as well…
On the structure and energetics of quasar broad absorption-line outflows
Fred Hamann, Hanna Herbst, Isabelle Paris +1
Quasar accretion-disk outflows might play an important role in galaxy evolution, but they are notoriously difficult to study due to line saturation and blending problems in the Ly-…
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 Composite Spectrum of BOSS Quasars Selected for Studies of the Lyman-alpha Forest
David W. Harris, Trey W. Jensen, Nao Suzuki +12
The Baryon Oscillation Spectroscopic Survey (BOSS) has collected more than 150,000 quasar spectra since 2009. Using this unprecedented sample, we create a com…
