48. Ultra High Energy Nuclei Propagation and the Spectrum of UHECR

Dr Roberto Aloisio (INAF - Osservatorio Arcetri Firenze)

15/02/2012, 12:10

talk

We will discuss the main features of ultra high energy nuclei propagation in the intergalactic space, presenting a novel analytical approach to pursue such studies. We will also discuss a new interpretation of the experimental observations of UHECR.

28. Transition from Galactic to Extragalactic Cosmic Rays and cosmic ray anisotropy

talk

We constrain the energy at which the transition from Galactic to extragalactic cosmic rays occurs by computing the anisotropy at Earth of cosmic rays emitted by Galactic sources. Since the diffusion approximation starts to loose its validity for E/Z >10^(16-17) eV, we propagate individual cosmic rays using Galactic magnetic field models and taking into account both their regular and turbulent...
