HYPERION Year One: an X-ray preview of the titans among primeval quasars
Abstract
The prodigious mass growth of the Supermassive Black Holes powering the first luminous quasars (QSO) at the Epoch of Reionization (EoR, z > 6) is a crucial and unsolved problem in modern extragalactic astrophysics. As such, QSO at EoR are being characterized through extensive multi-band campaigns with flagship observatories. So far the limited sensitivity of current X-ray observatories has only allowed a very poor characterisation of their nuclear properties. HYPERION is a recently approved 2.4 Ms Multi-Year Heritage XMM programme designed to overcome this limitation by significantly improving the X-ray characterization of the titans among QSO at EoR (i.e. the most luminous/massive at their epoch). The programme is expected to deliver unprecedented constraints on nuclear, accretion/ejection and disc/corona properties on a sample of 17 QSO. In this talk I will present results from the first year of XMM observations on the HYPERION programme.
