A low-frequency radio halo associated with a cluster of galaxies
G. Brunetti, S. Giacintucci, R. Cassano +7
Clusters of galaxies are the largest gravitationally bound objects in the Universe, containing about 10^15 solar masses of hot (10^8 K) gas, galaxies and dark matter in a typical v…
GMRT Radio Halo Survey in galaxy clusters at z = 0.2 -- 0.4. II.The eBCS clusters and analysis of the complete sample
T. Venturi, S. Giacintucci, D. Dallacasa +4
We present the results of the GMRT cluster radio halo survey. The main purposes of our observational project are to measure which fraction of massive galaxy clusters in the redshif…
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…
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…
The cosmic X-ray background and the population of the most heavily obscured AGNs
Filippo Frontera, Mauro Orlandini, Raffaella Landi +7
We report on an accurate measurement of the CXB in the 15-50 keV range performed with the Phoswich Detection System (PDS) instrument aboard the BeppoSAX satellite. We establish tha…
