ENERGY FEEDBACK FROM X-RAY BINARIES IN THE EARLY UNIVERSE
X-ray photons, because of their long mean-free paths, can easily escape the galactic environments where they are produced, and interact at long distances with the intergalactic medium, potentially having a significant contribution to the heating and reionization of the early universe. The two most important sources of X-ray photons in …
