Description
Diffuse radio sources, known as mini-halos and halos, are sometimes found at the centres of galaxy clusters, though both are rarely observed together. The origin of these sources remains unclear. In this talk I will present our investigation on the massive galaxy cluster RXJ 1347.5-1145, known to host a central mini-halo and possible extended emission. Using deep multi-frequency observations from MeerKAT and uGMRT, we confirm the presence of the central mini-halo, but discover an additional diffuse source extending up to 840 kpc that is classified as a giant radio halo. We examine the correlation between radio and X-ray brightness to understand the physical processes that govern the acceleration of radio-emitting relativistic electrons in these diffuse sources.
