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…

CHEX-MATE: Are we getting cluster thermodynamics right?

R. Seppi, D. Eckert, E. Rasia +19

Galaxy clusters offer powerful insights into the large-scale structure of the Universe and the physics of baryons in hot state. Their scientific exploitation, however, hinges on ou…

CHEX-MATE: New detections and properties of the radio diffuse emission in massive clusters with MeerKAT

M. Balboni, F. Gastaldello, A. Bonafede +18

Modern radio telescopes are revolutionising our understanding of non-thermal phenomena in galaxy clusters, collecting large samples of extended sources with unprecedented sensitivi…

CHEX-MATE: Relationship between X-ray and millimetre inferences of galaxy cluster temperature profiles

F. De Luca, H. Bourdin, P. Mazzotta +25

Thermodynamic profiles from X-ray and millimetre observations of galaxy clusters are often compared under the simplifying assumptions of smooth, spherically symmetric intracluster…

CHEX-MATE: towards a consistent universal pressure profile and cluster mass reconstruction

M. Muñoz-Echeverría, E. Pointecouteau, G. W. Pratt +31

In a self-similar paradigm of structure formation, the thermal pressure of the hot intra-cluster gas follows a universal distribution once the profile of each cluster is normalised…

The Peculiar Mini-Halo in the Shapley Supercluster Member Abell 3558

K. S. Trehaeven, T. Venturi, O. Smirnov +9

We present a multi-band study of the diffuse emission in the galaxy cluster Abell 3558, located in the core of the Shapley Supercluster. Using new MeerKAT UHF-Band and uGMRT Band-3…
