Deeply X-raying the Local Universe
Abstract
Swift/BAT and INTEGRAL/IBIS have revolutionized our view of Active Galactic Nuclei (AGN) in the local Universe. Their successful ongoing surveys count hundreds of AGN. However essential issues related to properties and evolution of AGN call for more sensitive surveys rather than larger numbers of AGN. To address these issues we have developed a new survey technique by merging the independent observations of BAT and IBIS/ISGRI: the Swift-INTEGRAL X-ray (SIX) survey. This survey capitalizes on the very uniform BAT sensitivity over the entire sky and the very deep sensitivity of IBIS/ISGRI over selected sky areas.We present the SIX survey technique and its results in terms of properties and evolution of AGN in the local Universe. Finally we will show our predictions and simulations for an approved 9 Ms survey performed by INTEGRAL/IBIS on a selected sky area. This will allow us to build with the SIX a reference sample of AGN in the local Universe in terms of redshift - luminosity parameter space. We discuss this in the context of the NuSTAR survey.
