Apparent effect of dust extinction on the observed outflow velocity of ionized gas in galaxy mergers
Naomichi Yutani, Yoshiki Toba, Keiichi Wada
In this study, we examine photoionization outflows during the late stages of galaxy mergers, with a specific focus on the relation between observed velocity of outflowing gas and t…
Circumnuclear Multi-phase Gas in the Circinus Galaxy. V. The Origin of the X-Ray Polarization in the Circinus Galaxy
Atsushi Tanimoto, Keiichi Wada, Yuki Kudoh +3
The Imaging X-ray Polarimetry Explorer (IXPE) detected X-ray polarization in the nearest Seyfert 2 galaxy, the Circinus galaxy, for the first time. To reproduce the IXPE results, w…
Self-consistent dust and non-LTE line radiative transfer with SKIRT
Kosei Matsumoto, Peter Camps, Maarten Baes +4
We introduce Monte Carlo-based non-LTE line radiative transfer calculations in the 3D dust radiative transfer code SKIRT, which was originally set up as a dust radiative transfer c…
Multi-phase gas nature in the sub-pc region of the active galactic nuclei II: Possible origins of the changing-state AGNs
Keiichi Wada, Yuki Kudoh, Tohru Nagao
Multi-wavelength observations of active galactic nuclei (AGNs) often reveal various time scales of variability. Among these phenomena, "changing-look AGNs" are extreme cases where…
