On the transition from Galactic to extragalactic cosmic-rays: spectral and composition features from two opposite scenarios
D. Allard, E. Parizot, A. V. Olinto
We study the phenomenology of cosmic-rays (CRs) at the galactic/extragalactic transition, focusing on two opposite models for the composition of the extragalactic (EG) component. M…
Extragalactic cosmic-ray source composition and the interpretation of the ankle
D. Allard, E. Parizot, A. V. Olinto +2
We consider the stochastic propagation of high-energy protons and nuclei in the cosmological microwave and infrared backgrounds, using revised photonuclear cross-sections and follo…
Photodisintegration of cosmic ray nuclei in galaxies and galaxy cluster radiation fields
T. A. Porter, D. Allard
We present the results of a new calculation for the photodisintegration of ultra-high energy cosmic ray nuclei on soft photon targets. We include all the relevant photodisintegrato…
UHE nuclei propagation and the interpretation of the ankle in the cosmic-ray spectrum
D. Allard, E. Parizot, E. Khan +2
We consider the stochastic propagation of high-energy protons and nuclei in the cosmological microwave and infrared backgrounds, using revised photonuclear cross-sections and follo…
