Double relics in Abell 2345 and Abell 1240: spectral index and polarization analysis
A. Bonafede, G. Giovannini, L. Feretti +2
The aim of the present work is to study the radio properties of double relics in Abell 1240 and Abell 2345 in the framework of double relic formation models. We present new Very La…
Low Luminosity Radio Loud Active Galactic Nuclei
G. Giovannini, M. Giroletti
I review observational properties of low power radio loud AGN. High resolution VLBI observations allow the estimate of the jet velocity and orientation with respect to the line of…
The intracluster magnetic field power spectrum in Abell 2255
F. Govoni, M. Murgia, L. Feretti +3
The goal of this work is to constrain the strength and structure of the magnetic field in the nearby cluster of galaxies A2255. At radio wavelengths A2255 is characterized by the p…
Diffuse radio sources in the cluster of galaxies Abell 548b
L. Feretti, M. Bacchi, O. B. Slee +4
We report extensive VLA and ATCA observations of the two diffuse radio sources in the cluster of galaxies Abell 548b, which confirm their classification as relics. The two relics (…
New radio halos and relics in clusters of galaxies
G. Giovannini, L. Feretti, F. Govoni +2
We present here new images of relics and halo sources in rich cluster of galaxies and the correlation between the halo radio surface brightness versus the cluster bolometric X-ray…
Magnetic Fields and Faraday Rotation in Clusters of Galaxies
M. Murgia, F. Govoni, L. Feretti +5
We present a numerical approach to investigate the relationship between magnetic fields and Faraday rotation effects in clusters of galaxies. We can infer the structure and strengt…
