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…
Non-thermal filaments and AGN recurrent activity in the galaxy group Nest200047: a LOFAR, uGMRT, MeerKAT, VLA radio spectral analysis
M. Brienza, K. Rajpurohit, E. Churazov +15
Nest200047 is a clear example of multiple radio bubbles from an Active Galactic Nucleus (AGN) in a galaxy group, featuring non-thermal filaments likely shaped by buoyancy, gas moti…
Decoding AGN Feedback with X-arithmetic: From Morphology to Physical Mechanisms
Hannah McCall, Irina Zhuravleva, Eugene Churazov +4
Feedback from Active Galactic Nuclei (AGN) is a key process in the evolution of massive halos in the Universe. New observational information on feedback is crucial for improving th…
Feeding and feedback processes in the Spiderweb proto-intracluster medium
M. Lepore, L. Di Mascolo, P. Tozzi +15
We present the detailed analysis of the thermal, diffuse emission of the proto-intracluster medium (ICM) detected in the halo of the Spiderweb Galaxy at z=2.16, within a radius of…
The Physalis system: Discovery of ORC-like radio shells around a massive pair of interacting early-type galaxies with offset X-ray emission
Bärbel S. Koribalski, Ildar Khabibullin, Klaus Dolag +7
We present the discovery of large radio shells around a massive pair of interacting galaxies and extended diffuse X-ray emission within the shells. The radio data were obtained wit…
