Parsec-scale properties of a complete sample of radio galaxies
T. Venturi, G. Giovannini, L. Feretti +2
We report the most important results on the parsec-scale properties of a complete sample of radio galaxies carried out at radio frequencies with the Global VLBI array and with the…
Non thermal emission from galaxy clusters: radio halos
L. Feretti, G. Brunetti, G. Giovannini +2
The number of diffuse radio halos in clusters of galaxies has grown in recent years, making it possible to derive statistical properties of these sources and of the hosting cluster…
Particle reacceleration in Coma cluster: radio properties and hard X-ray emission
G. Brunetti, G. Setti, L. Feretti +1
The radio spectral index map of the Coma halo shows a progressive steepening of the spectral index with increasing radius. Such a steepening cannot be simply justified by models in…
Radio Halos and Relics in Clusters of Galaxies and Detection Statistics
Gabriele Giovannini, Luigina Feretti, Federica Govoni
New sensitive VLA observations confirm the existence of halo and relic sources in 6 Abell clusters where a diffuse emission was found in the NVSS. We find evidence that the frequen…
Hard X-ray emission from the galaxy cluster A2256
R. Fusco-Femiano, D. Dal Fiume, S. De Grandi +6
After the positive detection by BeppoSAX of hard X-ray radiation up to ~80 keV in the Coma cluster spectrum, we present evidence for nonthermal emission from A2256 in excess of the…
The giant radio galaxy 8C0821+695 and its environment
L. Lara, K. -H. Mack, M. Lacy +5
We present new VLA and Effelsberg observations of the radio galaxy 8C0821+695. We have obtained detailed images in total intensity and polarization of this 2 Mpc sized giant. The m…
