A systematic search for rapid transients in the Subaru HSC-SSP transient survey
Seiji Toshikage, Masaomi Tanaka, Naoki Yasuda +9
Recent high-cadence transient surveys have discovered rapid transients whose light curve timescales are shorter than those of typical supernovae. In this paper, we present a system…
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…
Challenging the AGN scenario for JWST/NIRSpec LRD and non-LRD broad H emitters in light of non-detection of NIRCam photometric variability and X-ray
Mitsuru Kokubo, Yuichi Harikane
JWST has uncovered a substantial population of high- () galaxies exhibiting broad H emission line with a Full Width at Half Maximum exceeding 1,000 km/s. This po…
Updated Picture of the Active Galactic Nuclei with Dusty/Dust-free Gas Structures and Effects of the Radiation Pressure
Shoichiro Mizukoshi, Takeo Minezaki, Hiroaki Sameshima +5
This study investigates the properties of two gas structures of X-ray selected active galactic nuclei (AGNs), that is, dusty and dust-free gas components, by separating them with t…
Optical Variability of Blazars in the Tomo-e Gozen Northern Sky Transient Survey
TianFang Zhang, Mamoru Doi, Mitsuru Kokubo +14
We studied the optical variability of 241 BL Lacs and 83 flat-spectrum radio quasars (FSRQ) from the 4LAC catalog using data from the Tomo-e Gozen Northern Sky Transient Survey, wi…
X-ray Winds In Nearby-to-distant Galaxies (X-WING) - I: Legacy Surveys of Galaxies with Ultrafast Outflows and Warm Absorbers in -
Satoshi Yamada, Taiki Kawamuro, Misaki Mizumoto +10
As an inaugural investigation under the X-ray Winds In Nearby-to-distant Galaxies (X-WING) program, we assembled a dataset comprising 132 active galactic nuclei (AGNs) spanning red…
The relationship of SMBHs and host galaxies at in the deep optical variability-selected AGN sample in the COSMOS field
Atsushi Hoshi, Toru Yamada, Mitsuru Kokubo +2
We present the study on the relationship between SMBHs and their host galaxies using our variability-selected AGN sample () constructed from t…
