The Contribution of Quasar Absorption Outflows to AGN Feedback
Determining the distance of quasar absorption outflows from the central source and their kinetic luminosity are crucial for understanding their contribution to AGN feedback.
Here we summarize the results for a sample of nine luminous quasars that were observed with the Hubble Space Telescope. We find that the outflows in more than half of the objects are powerful enough to be the main agents for AGN feedback. The sample is representative of the quasar absorption outflow population as a whole and is unbiased towards specific distance ranges or kinetic luminosity value. Therefore, the analysis results can be extended to the majority of such objects, including broad absorption line quasars (BALQSO).
