Measurements of magnetic fields in circumnuclear matter with the SKA telescopes
Satoko Sawada-Satoh, Yuki Kudoh
Magnetic fields are thought to regulate the angular momentum transfer in active galactic nuclei (AGNs), yet their strength and structure in circumnuclear regions remain poorly cons…
Probing the Parsec-Scale Dynamical Structure of Ionized Gas in Radio-Quiet AGN with SKA
Yuki Kudoh, Satoko Sawada-Satoh
We systematically organize the radio-emitting components in radio-quiet active galactic nuclei (RQ AGN), including jets, accretion disk coronae, dust, ionized gas outflows, and cir…
Unification Model of Active Galactic Nuclei by Photoionization Equilibrium Calculation Based on Radiative Hydrodynamic Simulations
Atsushi Tanimoto, Keiichi Wada, Yuki Kudoh +3
To investigate the origin of the dependence of the covering factor on the Eddington ratio suggested by X-ray observations, we examined the angular distribution of HI and HII based…
X-Ray Radiative Transfer Calculation Based on a Physics-based Model of the Sub-parsec-scale Gases around an Active Galactic Nucleus and Its Application to NGC 3783
Atsushi Tanimoto, Keiichi Wada, Hirokazu Odaka +2
Although the X-ray spectra of Seyfert 1 galaxies exhibit absorption lines of He-like iron and H-like iron at blue-shifted velocities of approximately $500 \ \mathrm{km} \ \mathrm{s…
Formation and Early Evolution of Protoplanetary Disks under Nonuniform Cosmic-Ray Ionization
Erika Nishio, Kengo Tomida, Yuki Kudoh +1
Angular momentum transport by magnetic fields is important for formation and evolution of protoplanetary disks. The effects of magnetic fields are suppressed due to non-ideal magne…
Multiphase Gas Nature in the Sub-parsec Region of the Active Galactic Nuclei. III. Eddington Ratio Dependence on the Structures of Dusty and Dust-free Outflows
Yuki Kudoh, Keiichi Wada, Nozomu Kawakatu +1
We investigated the influence of the Eddington ratio on sub-parsec-scale outflows in active galactic nuclei (AGNs) with supermassive black holes (SMBHs) masses of M$_{\odot}…
