Sloshing Motions in Abell 3571 Revealed by XRISM/Resolve Velocity Mapping
Itsuki Aihara, Congyao Zhang, Sora Nakajima +12
Minor mergers can induce sloshing motions in the intracluster medium, leaving characteristic signatures in the thermodynamic structure and gas kinematics of cluster cores. Abell 35…
Kinematics of Weak Cool-Core Cluster A3571 Observed with XRISM: Low Cooling Rate Balanced by Low Heating Rate
Hannah McCall, Irina Zhuravleva, Kyoko Matsushita +10
Most XRISM galaxy cluster observations to date have focused on AGN feedback or actively merging systems. The weak cool-core cluster A3571 was observed in four XRISM Cycle 1 pointin…
The major cluster merger in Abell 2034 as seen by XRISM: Strong turbulence and spectral anomalies?
Annie Heinrich, Irina Zhuravleva, Eugene Churazov +5
XRISM observations to date have shown that gas kinetic pressures in the intracluster medium (ICM) tend towards the low end of predictions from cosmological simulations. Here, we pr…
Dynamics of AGN feedback in the X-ray bright East and Southwest arms of M87, mapped by XRISM
A. Simionescu, C. Kilbourne, H. R. Russell +24
As the central galaxy in the nearest cluster, M87 provides the best spatial resolution for disentangling the complex interactions between AGN jets and the surrounding environment.…
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…
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…
