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…
Gas motion in the intracluster medium of the Virgo cluster replica
Théo Lebeau, Stefano Ettori, Jenny G. Sorce +2
Within the deep gravitational potential of galaxy clusters lies the intracluster medium (ICM). At the first order, it is considered to be at hydrostatic equilibrium within the pote…
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…
The impact of strong feedback on galaxy group scaling relations
D. Eckert, R. Seppi, J. Braspenning +16
Feedback from active supermassive black holes alters the distribution of matter in the Universe by injecting energy in the neighbouring hot gaseous medium, which leads to ejection…
Gas rotation and turbulence in the galaxy cluster Abell 2029
T. Bartalesi, A. Simionescu, S. Ettori +4
We constrain the rotation and turbulent support of the intracluster medium (ICM) in Abell 2029 (A2029), using dynamical equilibrium models and a combination of state-of-the-art X-r…
The stellar-to-halo mass relation of central galaxies across three orders of halo mass
Victoria Toptun, Paola Popesso, Ilaria Marini +9
The stellar content of galaxies is tightly connected to the mass and growth of their host dark matter halos. Observational constraints on this relation remain limited, particularly…
