We report the discovery of a luminous quasar, J1007+2115 at z = 7.515 (“Pōniuā‘ena”), from our wide-field reionization-era quasar survey. J1007+2115 is the second quasar now known at z > 7.5, deep into the reionization epoch. The quasar is powered by a (1.5 ± 0.2) × 109 M⊙ supermassive black hole (SMBH), based on its broad Mg ii emission-line profile from Gemini and Keck near-IR spectroscopy. The SMBH in J1007+2115 is twice as massive as that in quasar J1342+0928 at z = 7.54, the current quasar…

A Significantly Neutral Intergalactic Medium Around the Luminous z = 7 Quasar J0252–0503

Luminous z ≥ 7 quasars provide direct probes of the evolution of supermassive black holes (SMBHs) and the intergalactic medium (IGM) during the epoch of reionization (EoR). The Lyα damping wing

An 800-million-solar-mass black hole in a significantly neutral Universe at a redshift of 7.5

TLDR
Strong evidence of absorption of the spectrum of the quasar redwards of the Lyman α emission line (the Gunn–Peterson damping wing), as would be expected if a significant amount of the hydrogen in the intergalactic medium surrounding J1342 + 0928 is neutral, and a significant fraction of neutral hydrogen is derived, although the exact fraction depends on the modelling.

A luminous quasar at a redshift of z = 7.085

TLDR
Observations of a quasar at a redshift of 7.3 are reported, suggesting that the neutral fraction of the intergalactic medium in front of ULAS J1120+0641 exceeded 0.1.
