Crossing the Rubicon of Reionization with z~5 QSOs
A. Grazian, K. Boutsia, E. Giallongo +12
One of the key open questions in Cosmology is the nature of the sources that completed the cosmological hydrogen Reionization at z~5.2. High-z primeval galaxies have been long cons…

HYPerluminous quasars at the Epoch of ReionizatION (HYPERION). A new regime for the X-ray nuclear properties of the first quasars
L. Zappacosta, E. Piconcelli, F. Fiore +40
The existence of luminous quasars (QSO) at the Epoch of Reionization (EoR; i.e. z>6) powered by supermassive black holes (SMBH) with masses challenges models…
