The ultradeep survey in the CDFS: an XMM-Newton legacy

We propose an ultradeep (2.5 Ms) XMMNewton exposure in the Chandra Deep FieldSouth (CDFS) providing the most sensitive view of the hard Xray sky. TheXMMNewton highenergy throughput will return highquality Xray spectra formore than 100 heavily obscured (logNh larger than 23) AGN. We will study with anunprecedented detail obscured and ComptonThick AGN at the redshift peak oftheir activity (zvirgul12), characterize the average profile and intensity of theiron line and, thanks to the excellent multiwavelength coverage, assess the roleof accreting SMBHs in the context of galaxy evolution. This project, targeting anew unexplored discovery space, will create an XMMNewton legacy and apathfinder for future Xray missions. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
