Confirmation of non-thermal hard X-ray excess in the Coma cluster from two epoch observations
Roberto Fusco-Femiano, Mauro Orlandini, Gianfranco Brunetti +4
We report the hard X-ray spectrum of the Coma cluster obtained using the PDS data of two independent BeppoSAX observations performed with a time interval of about three years. In b…
Alfvenic reacceleration of relativistic particles in galaxy clusters: MHD waves, leptons and hadrons
Gianfranco Brunetti, Pasquale Blasi, Rossella Cassano +1
There is a growing evidence that extended radio halos are most likely generated by electrons reaccelerated via some kind of turbulence generated in the cluster volume during major…
Particle acceleration in cooling flow clusters of galaxies: the case of Abell 2626
Myriam Gitti, Gianfranco Brunetti, Luigina Feretti +1
It has recently been proposed a theoretical model which accounts for the origin of radio mini-halos observed in some cooling flow clusters as related to electron re-acceleration by…
Cooling Flows and Radio Mini-Halos in Clusters of Galaxies
Myriam Gitti, Gianfranco Brunetti, Giancarlo Setti +1
We apply to radio mini-halo candidates a model for electron re-acceleration in cooling flows (Gitti, Brunetti & Setti 2002). In agreement with the basic idea of the model, we find…
In-Situ Particle Acceleration in Extragalactic Radio Hot Spots: Observations Meet Expectations
G. Brunetti, K. -H. Mack, M. A. Prieto +1
We discuss, in terms of particle acceleration, the results from optical VLT observations of hot spots associated with radio galaxies. On the basis of observational and theoretical…
X-ray emission from GPS/CSS sources
Aneta Siemiginowska, Thomas L. Aldcroft, Jill Bechtold +3
The high spatial resolution of the Chandra X-ray Observatory allows us to study the environment of GPS/CSS sources to within an arcsec of the strong compact core. We present the di…
Chandra Discovery of an X-ray jet and Extended X-ray Structure in z=0.63 quasar, B2 0738+313
Aneta Siemiginowska, Carlo Stanghellini, Gianfranco Brunetti +8
We have made a 30 ksec Chandra observation of the redshift z=0.63 GPS quasar B2 0738+313. We detected X-ray emission from the core and have discovered a 200 kpc (projected on the s…
Inverse Compton X-rays from the radio galaxy 3C 219
A. Comastri, G. Brunetti, D. Dallacasa +3
We report the results from a Chandra observation of the powerful nearby (z=0.1744) radio galaxy 3C 219. We find evidence for non-thermal X-ray emission from the radio lobes which f…
The radio halo in the merging cluster A3562
T. Venturi, S. Bardelli, D. Dallacasa +4
we present new VLA observations at 1.4 GHz confirming the presence of a radio halo at the centre of the cluster A3562, in the core of the Shapley Concentration. We also report a de…
