Journal ArticleDOI
The Coma cluster magnetic field from Faraday rotation measures
Annalisa Bonafede,L. Feretti,Matteo Murgia,Federica Govoni,Gabriele Giovannini,Daniele Dallacasa,Klaus Dolag,G. B. Taylor +7 more
TL;DR: In this article, the authors derived the magnetic field strength and power spectrum of the Coma cluster magnetic field from the Faraday rotation measure (RM) images with numerical simulations of magnetic field.
Journal ArticleDOI
Magnetic fields and Faraday rotation in clusters of galaxies
Matteo Murgia,Federica Govoni,L. Feretti,Gabriele Giovannini,Daniele Dallacasa,Roberto Fanti,G. B. Taylor,Klaus Dolag +7 more
TL;DR: In this article, a numerical approach is presented to investigate the relationship between magnetic fields and Faraday rotation effects in clusters of galaxies. But the results show that the standard analytic expressions applied in the literature overestimate the cluster magnetic field strength by a factor of ∼2.
Journal ArticleDOI
A low-frequency radio halo associated with a cluster of galaxies
Gianfranco Brunetti,Simona Giacintucci,Simona Giacintucci,Rossella Cassano,W. M. Lane,Daniele Dallacasa,Tiziana Venturi,Namir E. Kassim,Giancarlo Setti,Giancarlo Setti,W. D. Cotton,Maxim Markevitch +11 more
TL;DR: In this paper, a radio halo at low frequencies associated with the merging cluster Abell 521 is reported, which is consistent with a secondary origin of the relativistic electrons, but instead supports turbulent acceleration.
Journal ArticleDOI
GMRT radio halo survey in galaxy clusters at z = 0.2–0.4 - II. The eBCS clusters and analysis of the complete sample
Tiziana Venturi,Simona Giacintucci,Simona Giacintucci,Daniele Dallacasa,Daniele Dallacasa,Rossella Cassano,Rossella Cassano,Gianfranco Brunetti,S. Bardelli,Giancarlo Setti,Giancarlo Setti +10 more
TL;DR: In this article, the authors presented the results of the GMRT cluster radio halo survey, which measured which fraction of massive galaxy clusters in the redshift range z = 0.2 −0.4 hosts a radio Halo, and constrain the expectations of the particle re-acceleration model for the origin of the non-thermal radio emission.
Journal ArticleDOI
GMRT radio halo survey in galaxy clusters at z = 0.2–0.4 - I. The REFLEX sub-sample
Tiziana Venturi,Simona Giacintucci,Simona Giacintucci,Gianfranco Brunetti,Rossella Cassano,Rossella Cassano,S. Bardelli,Daniele Dallacasa,Daniele Dallacasa,Giancarlo Setti,Giancarlo Setti +10 more
TL;DR: In this paper, the authors present the first results of an ongoing project devoted to the search of giant radio halos in galaxy clusters located in the redshift range z = 0.2-0.4.
