Mining for Protoclusters at z∼4 from Photometric Datasets with Deep Learning

Yoshihiro Takeda, Nobunari Kashikawa, Kei Ito +9

Protoclusters are high-z overdense regions that will evolve into clusters of galaxies by z=0, making them ideal for studying galaxy evolution expected to be accelerated by envi…

Environments around quasars at z∼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 z∼3, 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…
