The Concerted Impact of Galaxies and QSOs on the Ionization and Thermal State of the Intergalactic Medium

Koki Kakiichi, Luca Graziani, Benedetta Ciardi +4

We present a detailed analysis of the ionization and thermal structure of the intergalactic medium (IGM) around a high-redshift QSO using a large suite of cosmological, multi-frequ…

Cosmic Galaxy-IGM HI Relation at $z \sim 2 - 3$ Probed in the COSMOS/UltraVISTA $1.6$ deg $^{2}$ Field

Shiro Mukae, Masami Ouchi, Koki Kakiichi +7

We present spatial correlations of galaxies and IGM HI in the COSMOS/UltraVISTA 1.62 deg $^{2}$ field. Our data consist of 13,415 photo- $z$ galaxies at $z \sim 2 - 3$ with $K_{s} < 23.4$ and…
