Monitoring the power spectrum of magnetic field fluctuations across the simulated intracluster medium
T. Bartalesi, F. Vazza, S. Ettori +2
Thanks to the current and forthcoming radio interferometers, Faraday rotation measure maps extend out to the outskirts of galaxy clusters. Interpreted through models of the magneti…
CHEX-MATE: X-ray surface brightness discontinuities across a representative cluster sample
Maria Giulia Campitiello, Stefano Ettori, Lorenzo Lovisari +20
We analyze the presence of X-ray surface brightness (SB) discontinuities, such as shocks and cold fronts, in the intracluster medium (ICM) of the 116 galaxy clusters from the CHEX-…
Energy deposited by black holes in the hot X-ray gas of elliptical galaxies, groups and clusters
A. Cattaneo, S. Ettori
Galaxy groups show entropy excesses with respect to theoretical expectations from models and simulations with purely gravitational heating. We determine the heat $Q_{\rm heat}…
Radio Halos in Galaxy Clusters as unveiled by the SKA telescope
R. Cassano, G. Di Gennaro, V. Cuciti +24
Giant radio halos (RHs) are diffuse, Mpc-scale synchrotron sources observed in a growing fraction of galaxy clusters. They trace relativistic particles and magnetic fields in the i…
The SKA View of Cool-core Clusters: Evolution of Radio Mini-halos and AGN Feedback
Myriam Gitti, Paolo Tozzi, Francesco Ubertosi +12
In about 70 per cent of relaxed, cool-core galaxy clusters, the brightest cluster galaxy (BCG) is radio loud, showing non-thermal radio jets and lobes ejected by the central active…
A high-dynamic-range view of the growth of structure and the warm/hot Universe
Luca Di Mascolo, Tony Mroczkowski, Joshiwa van Marrewijk +23
Baryons heat to temperatures above as they accrete onto massive overdensities -- galaxies, groups, clusters, and filaments -- where they ionize and become o…
