X-ray emission from a rapidly accreting narrow-line Seyfert 1 galaxy at z=6.56
Julien Wolf, Kirpal Nandra, Mara Salvato +14
This study aims at identifying luminous quasars at among X-ray-selected sources in the eROSITA Final Equatorial-Depth Survey (eFEDS) in order to place a lower limit on blac…
The physical origin for spatially large scatter of IGM opacity at the end of reionization: the IGM Ly opacity-galaxy density relation
Rikako Ishimoto, Nobunari Kashikawa, Daichi Kashino +9
The large opacity fluctuations in the Ly forest may indicate inhomogeneous progress of reionization. To explain the observed large scatter of the effective Ly optic…
Exploratory Study of Transverse Proximity Effect around BAL Quasars
Toru Misawa, Rikako Ishimoto, Satoshi Kobu +5
We aim to find out the reason why there exists an anisotropic HI absorption around quasars; i.e., the environments around quasars are highly biased toward producing strong HI absor…
CHORUS IV: Mapping the Spatially Inhomogeneous Cosmic Reionization with Subaru HSC
Takehiro Yoshioka, Nobunari Kashikawa, Akio K. Inoue +11
The spatial inhomogeneity is one of the important features for understanding the reionization process; however, it has not yet been fully quantified. To map this inhomogeneous dist…
