Cascade photons as test of protons in UHECR
V. Berezinsky, A. Gazizov, O. Kalashev
An isotropic component of high energy -ray spectrum measured by Fermi LAT constrains the proton component of UHECR. The strongest restriction comes from the highest, …
Transition from galactic to extragalactic cosmic rays
R. Aloisio, V. Berezinsky, A. Gazizov
The study of the transition between galactic and extragalactic cosmic rays can shed more light on the end of the Galactic cosmic rays spectrum and the beginning of the extragalacti…
Disappointing model for ultrahigh-energy cosmic rays
R. Aloisio, V. Berezinsky, A. Gazizov
Data of Pierre Auger Observatory show a proton-dominated chemical composition of ultrahigh-energy cosmic rays spectrum at (1 - 3) EeV and a steadily heavier composition with energy…
Restricting UHECRs and cosmogenic neutrinos with Fermi-LAT
V. Berezinsky, A. Gazizov, M. Kachelriess +1
Ultrahigh energy cosmic ray (UHECR) protons interacting with the cosmic microwave background (CMB) produce UHE electrons and gamma-rays that in turn initiate electromagnetic cascad…
Ultra High Energy Cosmic Rays: The disappointing model
R. Aloisio, V. Berezinsky, A. Gazizov
We develop a model for explaining the data of Pierre Auger Observatory (Auger) for Ultra High Energy Cosmic Rays (UHECR), in particular, the mass composition being steadily heavier…
Superluminal problem in diffusion of relativistic particles and its phenomenological solution
R. Aloisio, V. Berezinsky, A. Gazizov
We discuss the superluminal problem in the diffusion of ultra high energy protons with energy losses taken into account. The phenomenological solution of this problem is found with…
