The X-ray and optical analyses of A3667 indicate that it has undergone a recent subcluster merger event. We believe that the Mpc-scale radio sources identified in A3667 are also a consequence of the merger. Our previous numerical simulations show that mergers often produce large-scale shocks and turbulence capable of both magnetic field amplification and in-situ reacceleration of relativistic particles.
