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…
Implication of a galaxy-scale negative feedback by one of the most powerful multi-phase outflows in a hyper-luminous infrared galaxy at the intermediate redshift
Xiaoyang Chen, Masayuki Akiyama, Kohei Ichikawa +12
Powerful, galactic outflows driven by Active Galactic Nuclei (AGNs) are commonly considered as a main mechanism to regulate star formation in massive galaxies. Ultra- and hyper-lum…
Cross-correlation of Luminous Red Galaxies with ML-selected AGN in HSC-SSP: Unobscured AGN residing in more massive halos
Rodrigo Córdova Rosado, Andy D. Goulding, Jenny E. Greene +7
Active galactic nuclei (AGN) are the signposts of black hole growth, and likely play an important role in galaxy evolution. An outstanding question is whether AGN of different spec…
A Post-Starburst Pathway for the Formation of Massive Galaxies and Black Holes at z>6
Masafusa Onoue, Xuheng Ding, John D. Silverman +45
Understanding the rapid formation of supermassive black holes (SMBHs) in the early universe requires insight into stellar mass growth in host galaxies. Here, we present NIRSpec res…
Discovery of a hyperluminous quasar at z = 1.62 with Eddington ratio > 3 in the eFEDS field confirmed by KOOLS-IFU on Seimei Telescope
Yoshiki Toba, Keito Masu, Naomi Ota +17
We report the discovery of a hyperluminous type 1 quasar (eFEDS J082826.9-013911; eFEDSJ0828-0139) at = 1.622 with a super-Eddington ratio (). We perfor…
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…
Ongoing and fossil large-scale outflows detected in a high-redshift radio galaxy: [C II] observations of TN J09242201 at
Kianhong Lee, Masayuki Akiyama, Kotaro Kohno +13
We present Atacama Large Millimeter/submillimeter Array observations of the [C II] 158 m line and the underlying continuum emission of TN J09242201, which is one of the most…
Merging gas-rich galaxies that harbor low-luminosity twin quasars at z = 6.05: a promising progenitor of the most luminous quasars
Takuma Izumi, Yoshiki Matsuoka, Masafusa Onoue +15
We present ALMA [CII] 158 m line and underlying far-infrared (FIR) continuum emission observations ( resolution) toward a quasar-quasar pair system recentl…
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…
