Context. The Shapley Supercluster (〈z〉 ≈ 0.048) contains several tens of gravitationally bound clusters and groups, making it it is an ideal subject for radio studies of cluster mergers. Aims. We used new high sensitivity radio observations to investigate the less energetic events of mass assembly in the Shapley Supercluster from supercluster down to galactic scales. Methods. We created total intensity images of the full region between A 3558 and A 3562, from ∼ 230 to ∼ 1650 MHz, using ASKAP…
