Detection of anisotropic satellite quenching in galaxy clusters up to
Makoto Ando, Kazuhiro Shimasaku, Kei Ito
Satellite galaxies in the cluster environment are more likely to be quenched than galaxies in the general field. Recently, it has been reported that satellite galaxy quenching depe…
A Wide and Deep Exploration of Radio Galaxies with Subaru HSC (WERGS). IX. The Most Overdense Region at z~5 Inhabited by a Massive Radio Galaxy
Hisakazu Uchiyama, Takuji Yamashita, Tohru Nagao +13
We report on the galaxy density environment around a high-z radio galaxy (HzRG) at z=4.72, HSC J083913.17+011308.1 (HSC J0839+0113), probed using an r-dropout Lyman break galaxy (L…
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…
COSMOS2020: Ubiquitous AGN Activity of Massive Quiescent Galaxies at Revealed by X-ray and Radio Stacking
Kei Ito, Masayuki Tanaka, Takamitsu Miyaji +8
We characterize the average X-ray and radio properties of quiescent galaxies (QGs) with at . QGs are photometrically selected from the latest CO…
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…
A systematic search for galaxy protocluster cores at the transition epoch of their star formation activity
Makoto Ando, Kazuhiro Shimasaku, Rieko Momose +3
The redshift of is the transition epoch of protoclusters (PCs) from the star-forming phase into the quenching phase, and hence an appropriate era to investigate the buil…
