Valentina Vacca (INAF - Osservatorio Astronomico di Cagliari), "Observation of a nearby filament of galaxy clusters"

During this talk I will present radio observations of a region of the sky of 64 deg2, likely associated with a z?0.1 over-density traced by nine massive galaxy clusters. I will report about the detection in this region of diffuse synchrotron radio emission fainter and more extended than known diffuse large-scale synchrotron cluster sources. These sources could represent a new population connected to a large-scale filament of the cosmic web.
