Suppression of Radiative Cooling in Galaxy Cluster Cores by the Combination of AGN Heating and Sloshing
Yutaka Fujita, Tomoaki Matsumoto, Keiichi Wada
Recent XRISM observations suggest that gas mixing induced by sloshing contributes to core heating. We systematically investigate the suppression of cooling flows in galaxy cluster…
Broad line regions behind haze: Intrinsic shape of Br line and its origin in a type-1 Seyfert galaxy
Keiichi Wada, Tohru Nagao, Taro Shimizu +3
The broad-line region (BLR) of active galactic nuclei (AGN) is an essential component, yet its small size keeps its origin, structure, and kinematics uncertain. Infrared interferom…
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 $500 \ \mathrm{km} \ \mathrm{s…
Multiphase Gas Nature in the Sub-parsec Region of the Active Galactic Nuclei. III. Eddington Ratio Dependence on the Structures of Dusty and Dust-free Outflows
Yuki Kudoh, Keiichi Wada, Nozomu Kawakatu +1
We investigated the influence of the Eddington ratio on sub-parsec-scale outflows in active galactic nuclei (AGNs) with supermassive black holes (SMBHs) masses of M$_{\odot}…
