Diagnosing the Fe line complex of the intracluster medium by XRISM high-resolution spectroscopy
K. Fukushima, L. Hirata, N. Y. Yamasaki +17
We aim to test the validity of the CIE framework in the ICM by performing line diagnostics based mainly on resolved Fe-K emission lines. Methods. We analyse Resolve full-array spec…
Unravelling Turbulence and Magnetic Fields in Galaxy Clusters with SKA and XRISM
Kohei Kurahara, Takuya Akahori, Amit Seta +5
This chapter proposes a research framework to quantitatively investigate non-thermal components in the Intracluster Medium (ICM) of galaxy clusters, which are critical ingredients…
Kinetic structure of the intracluster medium across nearby clusters observed with XRISM
Naomi Ota, Erwin T. Lau, Satoshi Yamada +2
XRISM/Resolve is building a sample of galaxy clusters with directly measured ICM gas motions, revealing diverse projected dynamical states. We compile 45 XRISM/Resolve measurements…
XRISM-Subaru views of Abell 754: an off-axis, near-line-of-sight merging cluster
Nobuhiro Okabe, Yuki Omiya, Kazuhiro Nakazawa +4
We report a weak-lensing (WL) mass measurement for the merging cluster Abell 754 and impose constraints on the merger trajectory. The trajectory analysis adopts a two-body model wi…
XRISM Observations of The Prototypical Cold Front in Abell 3667
Yuki Omiya, Yuto Ichinohe, Kazuhiro Nakazawa +13
We present high-resolution X-ray spectroscopy of the merging galaxy cluster Abell 3667 with \textit{XRISM}/Resolve. Two observations, targeting the cluster X-ray core and the proto…
XRISM-Subaru views of Abell 754: Energetic ICM Motions Revealed by XRISM/Resolve
Yuki Omiya, Nobuhiro Okabe, Kazuhiro Nakazawa +4
We present high-resolution X-ray spectroscopy of the merging cluster Abell~754 using \textit{XRISM}/Resolve. In GO1 phase, \textit{XRISM}/Resolve observed Abell 754 in two deep poi…
