AGN photoionization of gas in companion galaxies as a probe of AGN radiation in time and direction
William C. Keel, Vardha N. Bennert, Anna Pancoast +9
We consider AGN photoionization of gas in companion galaxies (cross-ionization) as a way to sample the intensity of AGN radiation in both direction and time, independent of the gas…
A Local Baseline of the Black Hole Mass Scaling Relations for Active Galaxies. III. The BH mass - relation
Vardha N. Bennert, Tommaso Treu, Matthew W. Auger +6
We create a baseline of the black hole (BH) mass (MBH) - stellar-velocity dispersion (sigma) relation for active galaxies, using a sample of 66 local (0.02<z<0.09) Seyfert-1 galaxi…
The rise of SN2014J in the nearby galaxy M82
A. Goobar, J. Johansson, R. Amanullah +31
We report on the discovery of SN2014J in the nearby galaxy M82. Given its proximity, it offers the best opportunity to date to study a thermonuclear supernova over a wide range of…
