Kinetic Luminosity of Quasar Outflows and its Implications to AGN Feedback

Abstract: Sub-relativistic outflows are seen as blueshifted absorption troughs in the spectra of roughly one third of all quasars. I will describe recent results from VLT and HST observations, that yield the mass flux and kinetic luminosity for representative outflows. The derived values suggest that quasar absorption outflows have a profound effect on their host galaxy and maybe the major agent of AGN feedback.
