X-ray Evolution of Galaxies Through the Eons: New Insight From Extragalactic Surveys

Studies of the extragalactic Universe, from ultraviolet to infrared wavelengths, have been extremely effective at piecing together a basic picture of how stars in galaxies evolved throughout cosmic history.  At X-ray wavelengths, galaxy emission is dominated by populations of X-ray binaries, which consist of black holes and neutron stars that are accreting material from normal stellar companions.  The cosmic history of X-ray binary emission contains unique information about how the properties of galaxies (e.g.,  star-formation activity, metallicities, and stellar ages), and their black hole and neutron star populations, evolved over cosmic time.  I will present new constraints on the redshift evolution of X-ray emission from galaxies using the 6 Ms Chandra Deep Field-South, the most sensitive X-ray survey of the Universe ever conducted, and discuss how our results have exciting new implications for the heating of the intergalactic medium in the very high redshift Universe (at redshifts z > 5).
