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…

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 (…

XMM-Newton Measurement of the Galactic Halo X-ray Emission using a Compact Shadowing Cloud

David B. Henley, Robin L. Shelton, Renata S. Cumbee +1

Observations of interstellar clouds that cast shadows in the soft X-ray background can be used to separate the background Galactic halo emission from the local emission due to sola…
