Gamma rays from clusters of galaxies
Pasquale Blasi, Stefano Gabici, Gianfranco Brunetti
Clusters of galaxies and the large scale filaments that connect neighboring clusters are expected to be sites of acceleration of charged particles and sources of non-thermal radiat…
Ultra High Energy Cosmic Rays
Pasquale Blasi
The detection of cosmic rays with energy around and in excess of eV raises many questions that future experiments will help answering to. I address here my view of some o…
The Effect of a Non-Thermal Tail on the Sunyaev-Zeldovich Effect in clusters of galaxies
P. Blasi, A. V. Olinto, A. Stebbins
We study the spectral distortions of the cosmic microwave background radiation induced by the Sunyaev-Zel'dovich (SZ) effect in clusters of galaxies when the target electrons have…
Cosmic Rays, Radio Halos and Non-Thermal X-ray Emission in Clusters of Galaxies
P. Blasi, S. Colafrancesco
We calculate the flux of radio, hard X-ray and UV radiation from clusters of galaxies as produced by synchrotron emission and Inverse Compton Scattering of electrons generated as s…
High Energy Phenomena in Clusters of Galaxies
P. Blasi, S. Colafrancesco
Several phenomena in high energy astrophysics have been recently related to clusters of galaxies and to cosmic ray interactions occurring inside these structures. In many of these…
Clusters of Galaxies and the Diffuse Gamma Ray Background
S. Colafrancesco, P. Blasi
We discuss the diffuse emission of gamma rays and neutrinos from galaxy clusters in the viable models for structure formation in the universe. We use a self-consistent picture for…
Signatures of Topological Defects
V. S. Berezinsky, P. Blasi, A. Vilenkin
We argue that due to various restrictions cosmic strings and monopole-string networks are not likely to produce the observed flux of ultra-high energy cosmic rays (UHECR). Among th…
