X-Ray Observations of Powerful AGN Outflows. Implications for Feedback

Pounds, Ken

Highly ionised winds with velocities ∼0.1-0.2 c were first detected in X-ray spectra of non-BAL AGN a decade ago. Subsequent observations and archival searches have shown such winds to be a common feature of luminous AGN, increasing the belief that powerful ionised winds have a wider importance in galaxy feedback models. Paradoxically, for the bes…
