A Wide and Deep Exploration of Radio Galaxies with Subaru HSC (WERGS). X. The Massive and Passive Nature of Radio Galaxies at
Yuta Yamamoto, Tohru Nagao, Takuji Yamashita +8
High- radio galaxies (HzRGs) are considered important objects for understanding the formation and evolution of massive galaxies in the early universe. However, till date, detail…
Mining for Protoclusters at from Photometric Datasets with Deep Learning
Yoshihiro Takeda, Nobunari Kashikawa, Kei Ito +9
Protoclusters are high- overdense regions that will evolve into clusters of galaxies by , making them ideal for studying galaxy evolution expected to be accelerated by envi…
Environments around quasars at 3 revealed by wide-field imaging with Subaru HSC and CFHT
Yuta Suzuki, Hisakazu Uchiyama, Yoshiki Matsuoka +7
We examine the local density environments around 67 quasars at , by combining the imaging data of Hyper Suprime-Cam Subaru Strategic Program (HSC-SSP) and Canada-France-Haw…
Galaxy properties from the outskirts to the core of a protocluster at z=3.699
Jun Toshikawa, Stijn Wuyts, Nobunari Kashikawa +6
We present follow-up spectroscopy on a protocluster candidate selected from the wide-field imaging of the Hyper SuprimeCam Subaru Strategic Programme. The target protocluster candi…
Cosmic Himalayas: The Highest Quasar Density Peak Identified in a 10,000 deg Sky with Spatial Discrepancies between Galaxies, Quasars, and IGM HI
Yongming Liang, Masami Ouchi, Dongsheng Sun +27
We report the identification of a quasar overdensity in the BOSSJ0210 field, dubbed Cosmic Himalayas, consisting of 11 quasars at , the densest overdensity of quasars…
