Asymmetric distribution of Fe-peak elements in Cassiopeia A revealed by XRISM

Toshiki Sato, Shin-ichiro Fujimoto, Koji Mori +20

The elemental abundances of the Fe-peak elements (such as Cr, Mn, Fe and Ni) and Ti are important for understanding the environment of explosive nuclear burning for the core-collap…

XRISM view of a stellar flare: High-resolution Fe K spectra of HR 1099, an RS CVn-type star

Miki Kurihara, Masahiro Tsujimoto, Michael Loewenstein +21

A high-resolution X-ray spectroscopic observation was made of the RS CVn-type binary star HR 1099 using the Resolve instrument onboard XRISM for its calibration purposes. During th…

Chlorine and Potassium Enrichment in the Cassiopeia A Supernova Remnant

XRISM collaboration

The elements in the universe are synthesized primarily in stars and supernovae, where nuclear fusion favors the production of even-Z elements. In contrast, odd-Z elements are less…

A laboratory plasma experiment for X-ray astronomy using a compact electron beam ion trap (EBIT)

Yuki Amano, Leo Hirata, Moto Togawa +11

We present the basic performance and experimental results of an electron beam ion trap (JAXA-EBIT), newly introduced to the Japanese astronomical community. Accurate atomic data ar…

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 (…
