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…

Chemical enrichment of the Perseus cluster core seen by XRISM/Resolve

XRISM Collaboration, Marc Audard, Hisamitsu Awaki +143

The intracluster medium (ICM) is rich in chemical elements, produced by core-collapse (SNcc) and Type Ia supernovae (SNIa) over the last 12 Gyr. Whereas cluster outskirts are…

Supersonic Motion in the Driving Region of M82

Skylar Grayson, Evan Scannapieco, Philipp Grete +5

The prototypical starburst galaxy M82 is host to an expansive, multiphase outflow whose driving mechanism is not fully understood. Longstanding models suggest that energy and mass…

Suppression of Radiative Cooling in Galaxy Cluster Cores by the Combination of AGN Heating and Sloshing

Yutaka Fujita, Tomoaki Matsumoto, Keiichi Wada

Recent XRISM observations suggest that gas mixing induced by sloshing contributes to core heating. We systematically investigate the suppression of cooling flows in galaxy cluster…

A Fast, Hot Wind from a Nuclear Starburst

XRISM Collaboration, Marc Audard, Hisamitsu Awaki +137

Galaxies with intense star formation often host multiphase, galaxy-scale winds powered by supernovae and fast stellar winds. These are strong enough to disrupt the star-forming int…

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…
