Powerful Outflows and Feedback from Active Galactic Nuclei

Pounds, Ken; King, Andrew

Active galactic nuclei (AGNs) represent the growth phases of the supermassive black holes in the center of almost every galaxy. Powerful, highly ionized winds, with velocities â¼0.1-0.2c, are a common feature in X-ray spectra of luminous AGNs, offering a plausible physical origin for the well-known connections between the hole and properties of it…
