Multiple shock fronts in RBS 797: the Chandra window on shock heating in galaxy clusters

F. Ubertosi, M. Gitti, F. Brighenti +11

Using 427 ks of Chandra observations, we present a study of shock heating and ICM cooling in the galaxy cluster RBS 797. We discover three nested pairs of weak shocks at roug…

Deep low-frequency radio observations of Abell 2256 II: The ultra-steep spectrum radio halo

K. Rajpurohit, E. Osinga, M. Brienza +17

We present the first detailed analysis of the radio halo in the merging galaxy cluster Abell 2256 using the LOFAR, uGMRT, and VLA. These observations combined with archival X-ray d…

The Planck clusters in the LOFAR sky. III. LoTSS-DR2: Dynamic states and density fluctuations of the intracluster medium

X. Zhang, A. Simionescu, F. Gastaldello +19

The footprint of LoTSS-DR2 covers 309 PSZ2 galaxy clusters, 83 of which host a radio halo and 26 host a radio relic(s). It provides us an excellent opportunity to statistically stu…

A deep study of A399-401: An application for wide-field facet calibration

J. M. G. H. J. de Jong, R. J. van Weeren, A. Botteon +6

We examine the particle acceleration mechanism in the Mpc-scale bridge between Abell 399 and Abell 401 and assess in particular if the synchrotron emission originates from first-or…

Life cycle of cosmic-ray electrons in the intracluster medium

F. Vazza, D. Wittor, L. Di Federico +5

We simulate the evolution of relativistic electrons injected into the medium of a small galaxy cluster by a central radio galaxy, studying how the initial jet power affects the dis…

Galaxy clusters enveloped by vast volumes of relativistic electrons

V. Cuciti, F. de Gasperin, M. Brueggen +12

The central regions of galaxy clusters are permeated by magnetic fields and filled with relativistic electrons. When clusters merge, the magnetic fields are amplified and relativis…
