Chemical enrichment in the Ophiuchus cluster core studied by high-resolution XRISM spectroscopy
Kotaro Fukushima, Yutaka Fujita, Kosuke Sato +2
Galaxy clusters provide an ideal laboratory for investigating the chemical enrichment history of the universe because they host the hot intracluster medium (ICM), which contains va…
Chemical composition and enrichment of the Centaurus cluster core seen by XRISM/Resolve
F. Mernier, K. Fukushima, A. Simionescu +16
Hot, X-ray emitting atmospheres pervading galaxy clusters are rich in metals, which have been synthesised and released by asymptotic giant branch (AGB) stars, core-collapse superno…
XRISM constraints on unidentified X-ray emission lines, including the 3.5 keV line, in the stacked spectrum of ten galaxy clusters
XRISM Collaboration, Marc Audard, Hisamitsu Awaki +150
We stack 3.75 Megaseconds of early XRISM Resolve observations of ten galaxy clusters to search for unidentified spectral lines in the 2.5-15 keV band (rest frame), including t…
Comparing XRISM cluster velocity dispersions with predictions from cosmological simulations: are feedback models too ejective?
XRISM Collaboration, Marc Audard, Hisamitsu Awaki +147
The dynamics of the intra-cluster medium (ICM), the hot plasma that fills galaxy clusters, are shaped by gravity-driven cluster mergers and feedback from supermassive black holes (…
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 mock observations of simulated AGN jets in the core of a galaxy cluster
Mahiro Shirotori, Yutaka Fujita
Jets from active galactic nuclei (AGNs) are expected to heat the surrounding intracluster medium (ICM). We investigate how the interaction between jets and the ICM appears in high-…
