Complex Nuclear Structure in Seyfert 2 Galaxy NGC 4388 Revealed by XRISM Observation
Kanta Fujiwara, Yoshihiro Ueda, Shoji Ogawa +13
We report results from the simultaneous XRISM (183 ks) and NuSTAR (62 ks) observations of the Seyfert-2 galaxy NGC 4388. This AGN has the brightest Fe K line among Compton-thin,…
Accurate Determination of Chemical Abundances near a Supermassive Black Hole
The XRISM collaboration
The metal abundances in galactic nuclei carry key information on the history of star formation and mass transfer in central regions of galaxies. X-ray fluorescence analysis is a un…
XRISM Discovery of Multiple Ionized Fe-K Emission and Absorption Components in Centaurus A
Taishu Kayanoki, Yasushi Fukazawa, Junjie Mao +13
We present the first clear detection of ionized Fe-K emission and absorption components in the nearby radio galaxy Centaurus A, revealed by the high-resolution XRISM/Resolve detect…
IMPACTX: An X-ray Spectral Model for Polar Dust and Clumpy Torus
Kanta Fujiwara, Yoshihiro Ueda, Shoji Ogawa +2
We construct a generic X-ray spectral model for the reflection component from the clumpy torus and dusty gas in the polar region (polar dusty gas) in an active galactic nucleus (AG…
XRISM analysis of the complex Fe K line in Centaurus A
David Bogensberger, Yuya Nakatani, Tahir Yaqoob +14
We analyze the high-resolution XRISM/Resolve spectrum of the Fe K emission line of the nearest active galactic nucleus, in Centaurus A. The line features two narrow and resolved…
AGN outflows and their properties in Mrk 766 as revealed by KOOLS-IFU on the Seimei Telescope
Kyuseok Oh, Yoshihiro Ueda, Satoshi Yamada +10
We present the emission-line flux distributions and their ratios, as well as the gas outflow features, of the innermost 2 kpc region of the type 1 Seyfert galaxy Mrk 766, using the…
