Scientific paper

In recent years AGN outflows have gained strong interest as a main agent in AGN feedback scenarios. Determining the mass flux and kinetic luminosity from these outflows requires an accurate determination of the column densities as well as a distance estimate to the outflow. Using the brand new UV COS spectrograph on board of the HST, we obtained high S/N spectrum of IRAS F22456-5125 allowing us to derive the physical conditions as well as accurate distance determination for several components of the UV outflow.
