AGILE and Swift simultaneous observations of the blazar S50716+714 during the bright flare of October 2007
P. Giommi, S. Colafrancesco, S. Cutini +15
We present the results of a series of optical, UV, X-ray and gamma-ray observations of the BL Lac object S50716+714 carried out by the Swift and AGILE satellites in late 2007 when…
Testing the cosmic ray content in galaxy clusters
P. Marchegiani, G. C. Perola, S. Colafrancesco
The effective content of cosmic rays (CR) in galaxy clusters remains elusive. This paper aims to estimate a maximum production of both secondary relativistic electrons, SRE, and ga…
Where does the hard X-ray diffuse emission in clusters of galaxies come from?
S. Colafrancesco, P. Marchegiani, G. C. Perola
The surface brightness produced by synchrotron radiation in Clusters of Galaxies with a radio-halo sets a degenerate constraint on the magnetic field strength, the relativistic ele…
The Non-Thermal Sunyaev-Zel'dovich Effect in Clusters of Galaxies
S. Colafrancesco, P. Marchegiani, E. Palladino
In this paper we provide a general derivation of the non-thermal (as well as of the thermal) SZ effect in galaxy clusters which is exact in the Thomson limit to any approximation o…
