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…
The dynamical state of A548 from XMM-Newton data: X-ray and radio connection
L. Solovyeva, S. Anokhin, L. Feretti +5
We present a detailed study of the X-ray properties of the galaxy cluster Abell 548b (z=0.04), using XMM-Newton data, and discuss the connection between the thermal properties and…
Observations of extended radio emission in clusters
C. Ferrari, F. Govoni, S. Schindler +2
We review observations of extended regions of radio emission in clusters; these include diffuse emission in `relics', and the large central regions commonly referred to as `halos'.…
The intracluster magnetic field power spectrum in Abell 2382
D. Guidetti, M. Murgia, F. Govoni +5
The goal of this work is to put constraints on the strength and structure of the magnetic field in the cluster of galaxies A2382. We investigate the relationship between magnetic f…
In search of dying radio sources in the local universe
P. Parma, M. Murgia, H. R. de Ruiter +3
Up till now very few dying sources were known, presumably because the dying phase is short at centimeter wavelengths. We therefore have tried to improve the statistics on sources t…
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…
