Ionized absorption and the AGN inner stucture

Thanks to high resolution spectroscopy, the basic phenomenology of the ionized gas, outflowing from the vicinity of the black hole in AGNs, is now deeper understood. Here we present a spectral analysis on a sample of bright AGNs carried out by RGS on board of XMM-Newton, focusing on the issues that are still open, for instance the geometry of the outflowing system, the density of the gas and its connection with other AGN's environments, like the accretion disk and the broad line region.
