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…
