What we have learnt from the Chandra COSMOS Legacy Survey
Abstract
The Chandra COSMOS Legacy survey covers 2.2 sq deg of the COSMOS field with a uniform depth of 180 ks of exposure and yields a total of 4000 X-ray detected sources. The main goal of the survey was to study the population of high redshift sources, their host properties and their clustering. The data provide very good quality X-ray detections which allowed us to study the obscuration properties as function of redshift and luminosity and to reveal a significant population of Compton Thick AGN. Moreover, beside the X-ray detections, we used the multiwavelength catalogs to study, via stacking analysis, undetected galaxies revealing a population of obscured AGN among elliptical galaxies and intermediate mass black holes in dwarf galaxies. In this talk, I will give an overall summary of the work done and in progress and how these works can inform future mission studies.
