AGN evolution from wide extragalactic surveys: witnessing the impact of the large scale enviroment

Extragalactic X-ray surveys with XMM-Newton and Chandra have revealed the evolution of active galactic nuclei (AGN) across time and space. The analysis of X-ray fields targeted on galaxy clusters have shown that AGNs tend to be abundant in the outskirts of clusters, and their surface density drops towards the centers of galaxy clusters. This observation is similar to the transition galaxies under go as they fall into clusters. Namely, the removal of interstellar medium from galaxies depletes the cold gas reservoir essential for star-formation. With a combined 60 sq. deg. sky coverage and X-ray flux limit of about 10 ^{-15}erg/s/cm ^{2} the XXL and the X-COP surveys are unique laboratories to assess the transformation of AGN. Due to the large collecting area of XMM, ideal for providing extended sky coverage, and the ancillary multiwavelength photometric and spectroscopic data we are in position to probe the AGN population across different environments, from the field all the way into galaxy cluster cores. Our sample consists of 200 clusters with masses 10 ^{14}-10 ^{15} solar masses up to redshift of one and several thousands of AGN. In this talk, I will present the first direct determination of the X-ray luminosity function of AGN inside clusters and the field up to redshift of one and discuss the implications on the unified model of AGN.
