The spectral index image of the radio halo in the cluster Abell 520 hosting a famous bow shock
V. Vacca, L. Feretti, G. Giovannini +4
Synchrotron radio emission is being detected from an increasing number of galaxy clusters. Spectral index images are a powerful tool to investigate the origin, nature, and connecti…

The nature of the giant diffuse non-thermal source in the A3411-A3412 complex
G. Giovannini, V. Vacca, M. Girardi +3
VLA deep radio images at 1.4 GHz in total intensity and polarization reveal a diffuse non-thermal source in the interacting clusters A3411 - A3412. Moreover a small-size low power…
