Revised statistics of radio halos and the re-acceleration model
R. Cassano, G. Brunetti, T. Venturi +4
Aims. The statistical properties of radio halos can be used to discriminate among the possible models for their origin. Therefore an unbiased and exhaustive investigation in this d…
Cosmic rays and Radio Halos in galaxy clusters : new constraints from radio observations
G. Brunetti, T. Venturi, D. Dallacasa +4
Clusters of galaxies are sites of acceleration of charged particles and sources of non-thermal radiation. We report on new constraints on the population of cosmic rays in the Intra…
Hard X-rays from Galaxy Clusters and SIMBOL-X
G. Brunetti, R. Cassano, G. Setti
Non thermal emission from galaxy clusters demonstrates the existence of relativistic particles and magnetic fields in the Intra Cluster Medium (ICM). Present instruments do not all…
An X-ray view of Pictor A radio lobes: a spatially resolved study
G. Migliori, P. Grandi, G. C. G. Palumbo +2
A spatially resolved analysis of the lobes of the radio galaxy Pictor A has been performed for the first time starting from a 50 ksec XMM-Newton observation. Magnetic field, B_{IC}…
New scaling relations in cluster radio halos and the re-acceleration model
R. Cassano, G. Brunetti, G. Setti +2
In this paper we derive new expected scaling relations for clusters with giant radio halos in the framework of the re-acceleration scenario in a simplified, but physically motivate…
Radio Lobes of Pictor A: an X-ray spatially resolved Study
G. Migliori, P. Grandi, G. G. C. Palumbo +2
A new XMM observation has made possible a detailed study of both lobes of the radio galaxy Pictor A. Their X-ray emission is of non thermal origin and due to Inverse Compton scatte…
Compressible Turbulence in Galaxy Clusters: Physics and Stochastic Particle Re-acceleration
G. Brunetti, A. Lazarian
We attempt to explain the non-thermal emission arising from galaxy clusters as a result of the re-acceleration of electrons by compressible turbulence induced by cluster mergers. I…
Low-Frequency study of two clusters of galaxies: A2744 and A2219
E. Orru', M. Murgia, L. Feretti +6
Spectral index images can be used to constraint the energy spectrum of relativistic electrons and magnetic field distribution in radio halos and relics, providing useful informatio…
