| Abstract: |
We present the first mid-IR spectra of X-ray selected Type 2 QSOs ever taken. The objects have been selected according to their high intrinsic luminosities and column densities in the X-rays. We characterize their spectral properties, quantify the contribution of star formation in the hosts and of AGN to the combined light of these objects, and discuss the implications of our results on AGN unification models and on models of the cosmic infrared background and of the star formation history of the universe. |
