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…

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…

Rich and diverse molecular gas environments of closely-separated dual quasars viewed by ALMA

Shenli Tang, John D. Silverman, Zhaoxuan Liu +12

We present a study of the molecular gas in five closely-spaced ( kpc) dual quasars () at redshifts with the…

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…
