Multiphase Gas Structure in the Circumnuclear Region of NGC 5506 Observed with ALMA
Kana Takechi, Hiroshi Nagai, Nozomu Kawakatu +7
We present a study of the multiphase gas structure and kinematics of the circumnuclear disk (CND) of NGC 5506, a nearby edge-on Seyfert galaxy, at a spatial resolution of …
Discovery of an X-ray Luminous Radio-Loud Quasar at : A Possible Transitional Super-Eddington Phase
Sakiko Obuchi, Kohei Ichikawa, Satoshi Yamada +11
We report the multiwavelength properties of eFEDS J084222.9+001000 (hereafter ID830), a quasar at , identified as the most X-ray luminous radio-loud quasar in the eROSITA…
ALMA Sub-parsec Resolution Dense Molecular Line Observations of the NGC 1068 Nucleus
Masatoshi Imanishi, Bernd Vollmer, Yoshiaki Hagiwara +3
We present the results of our ALMA observations of the dense molecular HCN J=4-3 and HCO J=4-3 lines at 1 pc (14 mas) resolution in the nuclear region of…
Dynamical Mechanism of Episodic Gas Accretion to the Central Region of Spiral Galaxies
Naomichi Yutani, Nozomu Kawakatu, Takayuki Saitoh +1
We performed \textit{N}-body/SPH simulations of isolated spiral galaxies with various bulge-to-disk mass ratios () from 0.02 to 0.2 to investigate mass…
Multiphase Gas Nature in the Sub-parsec Region of the Active Galactic Nuclei. III. Eddington Ratio Dependence on the Structures of Dusty and Dust-free Outflows
Yuki Kudoh, Keiichi Wada, Nozomu Kawakatu +1
We investigated the influence of the Eddington ratio on sub-parsec-scale outflows in active galactic nuclei (AGNs) with supermassive black holes (SMBHs) masses of M$_{\odot}…
Multiphase Gas Nature in the Sub-parsec Region of the Active Galactic Nuclei I: Dynamical Structures of Dusty and Dust-free Outflow
Yuki Kudoh, Keiichi Wada, Nozomu Kawakatu +1
We investigated dusty and dust-free gas dynamics for a radiation-driven sub-pc scale outflow in an active galactic nucleus (AGN) associated with a supermassive black hole $10^7 M_\…
