Abstract:
Gas-rich galaxy protoclusters at z>2 are excellent laboratories to study the effect of environment on SMBH growth, the physics of inflowing gas, and the on-set of AGN feedback in overdense regions. We propose to observe with ACIS-I (710 ks in total) three protoclusters at z=2.3-3.2 that, due to their properties, will provide us with the best insights into such scientific issues. These structures were discovered as overdensities of sub-mm galaxies, Lya emitters, and confirmed AGN around bright QSOs. Moreover, enormous Lya nebulae (>200 kpc) have been detected in their central regions, pinpointing the presence of massive gas inflows. We aim at obtaining a complete census of AGN in the protoclusters, measuring the AGN contribution to Lya nebula powering, and detecting extended X-ray emission.
