Abstract: An early glimpse of black hole growth A study of archival X-ray data from the Chandra X-ray observatory provides a measure of black hole growth at the earliest epochs at which observations are possible, around 600 million years after the Big Bang, at a redshift of z = 6–8. The results imply that black holes grow in tandem with their host galaxies, starting from the earliest times. The most copiously accreting black holes are buried in significant amounts of gas and dust that absorb most radiation except for the highest energy X-rays, and do not contribute to the re-ionization of the Universe.
