Giulia Macario Colloquium -- Searching for diffuse large-scale radio emission in cluster of galaxies
A growing number of galaxy clusters is nowadays known to host diffuse, large-scale radio sources (up to Mpc and beyond), commonly grouped into radio halos, radio relics and mini-halos on the basis of their location and properties. Their steep-spectrum synchrotron emission probes the presence of non-thermal intracluster components (weak magnetic fields and relativistic particles), that can affect the thermodynamical evolution of the host clusters.
