Deep Sky Objects and the X-ray Background
Abstract
Deep observations of the X-ray Sky have now resolved most of the X-ray Background. Obscured active galaxies are a key component. The obscured objects which dominate at fluxes above 10-15 are discussed and models in which the growth of wind-blowing active nuclei determine both black hole and galaxy mass are presented. The power from accretion is large and can easily influence the gas in a host galaxy, as well as heat the intergalactic medium.
