Galactic absorption measured by X-ray observations of clusters of galaxies at the low Galactic latitude

Yumiko Anraku, Shigeo Yamauchi, Anje Yoshimoto +3

The amount of the interstellar gas in the Galaxy has been conventionally estimated through observations at various wavelengths. The estimation of the total hydrogen column density…

Narrow iron- and nickel-K absorption lines from the eclipsing low-mass X-ray binary AX~J1745.62901

Kojiro Tanaka, Yoshitomo Maeda, Ryota Tomaru +23

We report the presence of a highly ionized absorber in the transient, eclipsing low-mass X-ray binary AX J1745.6-2901, observed from Feb. 26 to 29, 2024 with XRISM's Resolve and Xt…

XMM-Newton observations of ten high-redshift CAMIRA clusters of galaxies

Naomi Ota, Ikuyuki Mitsuishi, Nobuhiro Okabe +9

We present results from XMM-Newton observations of ten high-redshift () galaxy clusters selected from the CAMIRA catalog based on high richness (). These m…

The unusual spectrum of the X-ray transient source XRISM J174610.8-290021 near the Galactic center

A. Yoshimoto, S. Yamauchi, M. Nobukawa +20

The Galactic center region was observed with the XRISM X-ray observatory during the performance verification phase in 2024 and a point-like X-ray source was detected with the X-ray…

Overionized plasma in the supernova remnant Sagittarius A East anchored by XRISM observations

XRISM Collaboration

Sagittarius A East is a supernova remnant with a unique surrounding environment, as it is located in the immediate vicinity of the supermassive black hole at the Galactic center, S…

AGN properties of ~1 million member galaxies of galaxy groups and clusters at z < 1.4 based on the Subaru Hyper Suprime-Cam survey

Yoshiki Toba, Aoi Hashiguchi, Naomi Ota +17

Herein, we present the statistical properties of active galactic nuclei (AGNs) for approximately 1 million member galaxies of galaxy groups and clusters, with 0.1 cluster redsh…

AGN number fraction in galaxy groups and clusters at z < 1.4 from the Subaru Hyper Suprime-Cam survey

Aoi Hashiguchi, Yoshiki Toba, Naomi Ota +20

One of the key questions on active galactic nuclei (AGN) in galaxy clusters is how AGN could affect the formation and evolution of member galaxies and galaxy clusters in the histor…
