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…
Anisotropic inverse Compton scattering in radio galaxies and particle energy distribution
G. Brunetti, G. Setti
In this talk we briefly review the inverse Compton (IC) scattering of nuclear photons in the lobes of radio galaxies and quasars. We concentrate on the possibility to test this mod…
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…
Extended X-ray emission from FRIIs and RL quasars
G. Setti, G. Brunetti, A. Comastri
We review the evidence that detectable fluxes of X-rays are produced by inverse Compton scattering of nuclear photons with the relativistic electrons in the radio lobes of strong F…
Particle reacceleration in the Coma cluster and the radio, EUV and hard X-ray emissions
G. Brunetti, L. Feretti, G. Giovannini +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…
X-ray emission from FRII's radio lobes and the relativistic particle content
G. Setti, G. Brunetti, A. Comastri
It is pointed out that copius X-rays from the lobes of FRII radio galaxies are expected as a natural consequence of the unification linking FRIIs and radio-loud quasars. The detect…
