Description
I will discuss our current knowledge of the very high redshift Universe, with a particular focus on the results recently obtained by the Chandra J1030 survey, whose depth allowed us to reach fluxes faint enough to explore a population of obscured high-z AGNs, searching for evolutionary trends of the AGN obscured fraction.
I will then present what the next generation of X-ray instruments (particularly AXIS and Athena) would be able to achieve in terms of characterizing the very high-z, heavily obscured AGNs, and how these facilities will nicely complement the results which eRosita will obtain in the 2020s.
