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…
A morphological comparison between giant radio halos and radio mini--halos in galaxy clusters
R. Cassano, M. Gitti, G. Brunetti
In this letter we present a morphological comparison between giant radio halos and radio mini-halos in galaxy clusters based on radio--X-ray luminosity, P_{1.4}-L_X, and radio lumi…
Shock acceleration as origin of the radio relic in A521?
S. Giacintucci, T. Venturi, G. Macario +6
We present new high sensitivity observations of the radio relic in A521 carried out with the Giant Metrewave Radio Telescope at 327 MHz and with the Very Large Array at 4.9 and 8.5…
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…
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…
