UHECRs from the Radio Lobes of AGNs
F. Fraschetti, F. Melia
We report a stochastic mechanism of particle acceleration from first principles in an environment having properties like those of Radio Lobes in AGNs. We show that energies $\sim 1…
On the acceleration of Ultra-High-Energy Cosmic Rays
Federico Fraschetti
Ultra High Energy Cosmic Rays (UHECRs) hit the Earth's atmosphere with energies exceeding eV. This is the same energy as carried by a tennis ball moving at 100 km/h, but…
The role of GRB 031203 in clarifying the astrophysical GRB scenario
Remo Ruffini, Maria Grazia Bernardini, Carlo Luciano Bianco +7
The luminosity and the spectral distribution of the afterglow of GRB 031203 have been presented within our theoretical framework, which envisages the GRB structure as composed by a…
GRB 050315: A step toward the uniqueness of the overall GRB structure and the true nature of long GRBs
Remo Ruffini, Maria Grazia Bernardini, Carlo Luciano Bianco +4
Using the Swift data of GRB 050315, we progress on the uniqueness of our theoretically predicted Gamma-Ray Burst (GRB) structure as composed by a proper-GRB (P-GRB), emitted at the…
On the physical processes which lie at the bases of time variability of GRBs
R. Ruffini, C. L. Bianco, P. Chardonnet +2
The relative-space-time-transformation (RSTT) paradigm and the interpretation of the burst-structure (IBS) paradigm are applied to probe the origin of the time variability of GRBs.…
