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…
XRISM Reveals a Kinematically Coherent Core System of the Nearby Cool-Core Cluster Abell 2199
Kazunori Suda, Kyoko Matsushita, Kosuke Sato +14
We present the results of a deep 251 ks XRISM/Resolve observation of the cool core of the galaxy cluster Abell 2199. From the integrated spectrum of the central Reso…
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…
A XRISM/Resolve view of the dynamics in the hot gaseous atmosphere of M87
XRISM Collaboration, M. Audard, H. Awaki +138
The XRISM/Resolve microcalorimeter directly measured the gas velocities in the core of the Virgo Cluster, the closest example of AGN feedback in a cluster. This proximity allows us…
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 (…
Revisiting thermodynamics at the outskirts of the Perseus cluster with Suzaku: importance of modeling the Hot Galactic gas
Kyoko Matsushita, Hayato Sugiyama, Masaki Ueda +5
The thermodynamic properties of the intracluster medium (ICM) at the outskirts of galaxy clusters provide valuable insights into the growth of the dark matter halo and the heating…
Revisiting the abundance pattern and charge-exchange emission in the M82 centre
K. Fukushima, S. B. Kobayashi, K. Matsushita
The interstellar medium (ISM) in starburst galaxies contains plenty of chemical elements synthesised by core-collapse supernova explosions. By measuring the abundances of these met…
The soft X-ray background with Suzaku II: Supervirial temperature bubbles?
Hayato Sugiyama, Masaki Ueda, Kotaro Fukushima +4
Observations of the hot X-ray emitting interstellar medium in the Milky Way are important for studying the stellar feedback and understanding the formation and evolution of galaxie…
O, Ne, Mg, and Fe Abundances in Hot X-Ray-emitting Halos of Galaxy Clusters, Groups, and Giant Early-type Galaxies with XMM-Newton RGS Spectroscopy
Kotaro Fukushima, Shogo B. Kobayashi, Kyoko Matsushita
Chemical elements in the hot medium permeating early-type galaxies, groups, and clusters make them an excellent laboratory for studying metal enrichment and cycling processes in th…
XMM-Newton view of the shock heating in an early merging cluster, CIZA J1358.94750
Y. Omiya, K. Nakazawa, K. Matsushita +10
CIZA J1358.9-4750 is a nearby galaxy cluster in the early phase of a major merger. The two-dimensional temperature map using XMM-Newton EPIC-PN observation confirms the existence o…
The soft X-ray background with Suzaku: I. Milky Way halo
Masaki Ueda, Hayato Sugiyama, Shogo B. Kobayashi +4
We present measurements of the soft X-ray background emission for 130 Suzaku observations at and obtained from 2005 to 2015, covering nearly…
Chemical enrichment in the cool core of the Centaurus cluster of galaxies
Kotaro Fukushima, Shogo B. Kobayashi, Kyoko Matsushita
Here we present results from over 500 kiloseconds Chandra and XMM-Newton observations of the cool core of the Centaurus cluster. We investigate the spatial distributions of the O,…
