Unveiling radio halos in galaxy clusters in the LOFAR era
R. Cassano, G. Brunetti, H. J. A. Rottgering +1
Giant radio halos are mega-parsec scale synchrotron sources detected in a fraction of massive and merging galaxy clusters. Radio halos provide one of the most important pieces of e…
A giant radio halo in the massive and merging cluster Abell 1351
S. Giacintucci, T. Venturi, R. Cassano +2
We report on the detection of diffuse radio emission in the X-ray luminous and massive galaxy cluster A1351 (z=0.322) using archival Very Large Array data at 1.4 GHz. Given its cen…
On the evolution of giant radio halos and their connection with cluster mergers
G. Brunetti, R. Cassano, K. Dolag +1
Giant radio halos are diffuse, Mpc-scale, synchrotron sources located in the central regions of galaxy clusters and provide the most relevant example of cluster non-thermal activit…
Testing the radio halo-cluster merger scenario. The case of RXCJ2003.5-2323
S. Giacintucci, T. Venturi, G. Brunetti +5
We present a combined radio, X-ray and optical study of the galaxy cluster RXCJ2003.5-2323. The cluster hosts one of the largest, most powerful and distant giant radio halos known…
Radio Halos From Simulations And Hadronic Models I: The Coma cluster
J. Donnert, K. Dolag, G. Brunetti +2
We use the results from a constrained, cosmological MHD simulation of the Local Universe to predict the radio halo and the gamma-ray flux from the Coma cluster and compare it to cu…
Deep 1.4 GHZ Follow Up of the Steep Spectrum Radio Halo in Abell 521
D. Dallacasa, G. Brunetti, S. Giacintucci +6
In a recent paper we reported on the discovery of a radio halo with very steep spectrum in the merging galaxy cluster Abell 521 through observations with the Giant Metrewave Radio…
