The most giant radio structures in the Universe
Description
One of the exciting results of the last years concerning the study of the large-scale structure is the discovery of long (3-5 Mpc) bridges of radio emission connecting pairs of interacting clusters. This is the first direct evidence of the existence of particle acceleration and magnetic field amplification mechanisms outside galaxy clusters. Non-thermal components spread over such vast extents probe the dynamics of large-scale structures and the mechanisms of energy dissipation therein. In my talk, I will discuss recent results on radio bridges, showing how their observation represents a step forward in the search of the radio signature of the magnetized cosmic web.
