Prime Focus Spectrograph on the Subaru Telescope: Overview of Science Operations
Masayuki Tanaka, Akira Arai, Wanqiu He +30
The paper presents the science operation framework for Prime Focus Spectrograph (PFS or 'Onohi'ula in its Hawaiian name) installed at the 8.2m Subaru Telescope on the summit of Mau…
Environment of SDSS quasars at explored by Subaru HSC
Kohei Shibata, Tohru Nagao, Hisakazu Uchiyama +5
The relationship between quasars and their galaxy environment is important for understanding the evolution of galaxies and supermassive black holes, but it is not fully understood.…
Cluster candidates with massive quiescent galaxies at
Tomokazu Kiyota, Makoto Ando, Masayuki Tanaka +7
Galaxy clusters are crucial to understanding role of the environment in galaxy evolution. However, due to their rarity, only a limited number of clusters have been identified at $z…
Galaxy Morphologies Revealed with Subaru HSC and Super-Resolution Techniques II: Environmental Dependence of Galaxy Mergers at z~2-5
Takatoshi Shibuya, Yohito Ito, Kenta Asai +8
We super-resolve the seeing-limited Subaru Hyper Suprime-Cam (HSC) images for 32,187 galaxies at z~2-5 in three techniques, namely, the classical Richardson-Lucy (RL) point spread…
