Cosmological simulation of a radio synchrotron bridge between pre-merging galaxy clusters
Kosuke Nishiwaki, Gianfranco Brunetti, Franco Vazza +1
Radio bridges are diffuse synchrotron emission observed between merging galaxy clusters. Recent radio observations have reported both detections and non-detections of radio bridges…
A MeerKAT view on galaxy clusters
G. Bernardi, T. Venturi, R. Cassano +8
Almost two decades of observations of radio emission in galaxy clusters have proven the existence of relativistic particles and magnetic fields that generate extended synchrotron e…
Cluster Radio Halos at the crossroads between astrophysics and cosmology in the SKA era
R. Cassano, G. Bernardi, G. Brunetti +16
Giant Radio Halos (RH) are diffuse, Mpc-sized, synchrotron radio sources observed in a fraction of merging galaxy clusters. The current scenario for the origin of RHs assumes that…
Testing Secondary Models for the Origin of Radio Mini-Halos in Galaxy Clusters
John ZuHone, Gianfranco Brunetti, Simona Giacintucci +1
We present an MHD simulation of the emergence of a radio minihalo in a galaxy cluster core in a "secondary" model, where the source of the synchrotron-emitting electrons is hadroni…
Turbulence, Reconnection and Cosmic Rays in Galaxy Clusters
A. Lazarian, G. Brunetti
Recent years have been marked by substantial changes in our understanding of magnetic turbulence and magnetic reconnection, which, in its turn induced better understanding of cosmi…
Particle reacceleration by compressible turbulence in galaxy clusters: effects of reduced mean free path
G. Brunetti, A. Lazarian
Direct evidence for in situ particle acceleration mechanisms in the inter-galactic-medium (IGM) is provided by the diffuse Mpc--scale synchrotron emissions observed from galaxy clu…
