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…
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…
Quasar Luminosity Function at z = 7
Yoshiki Matsuoka, Masafusa Onoue, Kazushi Iwasawa +41
We present the quasar luminosity function (LF) at , measured with 35 spectroscopically confirmed quasars at . The sample of 22 quasars from the Subaru High-…
Narrow Fe-K Reverberation Mapping Unveils the Deactivated Broad-Line Region in a Changing-Look Active Galactic Nucleus
Hirofumi Noda, Taisei Mineta, Takeo Minezaki +11
"Changing-look active galactic nuclei" (CLAGNs) are known to change their apparent types between types 1 and 2, usually accompanied by a drastic change in their luminosity on times…
Measurement of AGN dust extinction based on the near-infrared flux variability of WISE data
Shoichiro Mizukoshi, Takeo Minezaki, Shoichi Tsunetsugu +4
We present the measurement of the line-of-sight extinction of the dusty torus for a large number of obscured active galactic nuclei (AGNs) based on the reddening of the colour of t…
Detection of highly correlated optical and X-ray variations in SS Cygni with Tomo-e Gozen and NICER
Y. Nishino, M. Kimura, S. Sako +8
We report on simultaneous optical and X-ray observations of the dwarf nova SS Cyg with Tomo-e Gozen/1.05 m Kiso Schmidt and Neutron star Interior Composition ExploreR (it NICER) /…
