X-Ray Selected Type 2 QSOs and Their Host Galaxies

Description	We present a large sample of X-ray selected type 2 QSOs from the XMM–COSMOS survey. Type 2 QSOs are luminous AGN whose central engines are obscured by large amounts of gas and dust. The selection criteria we have used are based on high X-ray luminosity $(L_{X}$ > $10^{44}$ erg $s^{−1}$) and heavy obscuration $(N_{H}$ > $10^{22}$ $cm^{−2}$). We derived stellar masses and star-formation rate estimates for the host galaxies from the best fit of the observed photometry. Type 2 QSOs are generally hosted in massive galaxies with on-going star formation.
