Measuring Kinetic luminosity of quasar outflows: results from VLT observations, and implications to AGN feedback
Sub-relativistic outflow are seen as blueshifted absorption troughs in the spectra of roughly a third of all quasars.I will describe a research program whose main aim is to determine the kinetic luminosity of these outflows, which is the key parameter to assess their contribution to the evolution of quasars/host galaxies and other AGN feedback scenarios.

Refreshments will be served in CP 155 at 3:15 PM
