Description
Shock waves driven by merger events can continuously source self-generated magnetic fields at the periphery of galaxy clusters. Diffuse non-thermal emission and polarization measurements from radio relics indicate a magnetisation of the intracluster medium due to merger shocks in addition to particle acceleration at the shock site. I will outline the growth and saturation of such magnetic fields, describe how they can explain the long-standing discrepancy between radio and X-ray observations of these objects, and make the case for a novel astrophysical search strategy for light dark matter species.
