Galaxy and AGN Evolution in the MIR: a combined Spitzer and X-ray view
Abstract
A proper analysis of the evolution of sources emitting in the Mid-Infrared is strongly dependent on their broad-band spectral properties (SEDs) at different redshifts and luminosities and on a reliable classification allowing to disentangle AGN from star-formation activity. The diagnostic diagrams based on the optical line ratios are often ambiguous and/or misleading not allowing a proper separation of the galaxy/AGN populations. Thanks to the combination of deep Spitzer and X-rays data a much better census of the hidden AGN activity and dust-obscured star-forming galaxies can be obtained, constraining galaxy and AGN evolutionary models.
