'Kinetic Luminosity of Quasar Outflows and its Implications to AGN Feedback: VLT/Xshooter and HST/COS Observations'
Nahum Arav,
Virginia Tech,
Sub-relativistic outflows are seen as blueshifted absorption troughs in the spectra of roughly one third of all quasars. I will describe a recent breakthrough, enabled by HST/COS observations, that yield the mass flux and kinetic luminosity for the majority of these outflows. The derived values suggest that quasar absorption outflows have a profound effect on the host galaxy.
