Description
Diffuse radio emission is now observed in many galaxy clusters. Depending on the morphology and properties of the emission, such sources are generally classified as radio (mini) halos, relics, and bridges. These synchrotron sources traces relativistic particles and magnetic fields that are accelerated and amplified in the intra-cluster medium (ICM) through a complex chain of mechanisms, which convert kinetic energy from cluster-scale motions down to the particle scale.
In this talk, I will present recent results from MeerKAT observations of galaxy clusters in different dynamical states, all characterized by the presence of diffuse radio emission in the ICM. In particular, I will highlight what is the step forward led by these new observations and discuss the likely formation scenarios of the sources presented.
