Discovery of extreme [OIII]5007A outflows in high-redshift red quasars
Nadia L. Zakamska, Fred Hamann, Isabelle Pâris +7
Black hole feedback is now a standard component of galaxy formation models. These models predict that the impact of black hole activity on its host galaxy likely peaked at z=2-3, t…
Constraining FeLoBAL outflows from absorption line variability
S. M. McGraw, J. C. Shields, F. W. Hamann +3
FeLoBALs are a rare class of quasar outflows with low-ionization broad absorption lines (BALs), large column densities, and potentially large kinetic energies that might be importa…
On the origins of C IV absorption profile diversity in broad absorption line quasars
Alexei Baskin, Ari Laor, Fred Hamann
There is a large diversity in the C IV broad absorption line (BAL) profile among BAL quasars (BALQs). We quantify this diversity by exploring the distribution of the C IV BAL prope…
The Host Galaxies and Narrow Line Regions of Four Double-Peaked [OIII] AGN
C. Villforth, F. Hamann
Major gas-rich mergers of galaxies are expected to play an important role in triggering and fuelling luminous AGN. We present deep multi-band (u/r/z) imaging and long slit spectros…
