Scientific paper

We propose to observe a set of 13 new IBIS/ISGRI sources extracted from a sample of 50 AGN selected by INTEGRAL in the 20-100 keV band. These bright objects have no X-ray spectroscopic information below 10 keV. XMM-Newton observations will allow us to cover the missing information in the 0.1-10 keV energy band for these objects in order to characterize their broad band emission. We aim at estimating their intrinsic absorption so to provide the nH distribution of the entire sample of 50 INTEGRAL AGN and infer the ratio of absorbed versus unabsorbed objects in the local Universe. We estimate that an exposure of 10 ks for each source for a total time of 130 ks, is sufficient to reach the goal of the present proposal.
