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…
AGN properties of ~1 million member galaxies of galaxy groups and clusters at z < 1.4 based on the Subaru Hyper Suprime-Cam survey
Yoshiki Toba, Aoi Hashiguchi, Naomi Ota +17
Herein, we present the statistical properties of active galactic nuclei (AGNs) for approximately 1 million member galaxies of galaxy groups and clusters, with 0.1 cluster redsh…
AGN number fraction in galaxy groups and clusters at z < 1.4 from the Subaru Hyper Suprime-Cam survey
Aoi Hashiguchi, Yoshiki Toba, Naomi Ota +20
One of the key questions on active galactic nuclei (AGN) in galaxy clusters is how AGN could affect the formation and evolution of member galaxies and galaxy clusters in the histor…
Optical IFU Observations of GOALS Sample with KOOLS-IFU on Seimei Telescope: Initial results of 9 U/LIRGs at 0.04
Yoshiki Toba, Satoshi Yamada, Kazuya Matsubayashi +23
We present ionized gas properties of 9 local ultra/luminous infrared galaxies (U/LIRGs) at 0.04 through IFU observations with KOOLS-IFU on Seimei Telescope. The observed targ…
