Implications of the cosmic ray spectrum for the mass composition at the highest energies
D. Allard, N. G Busca, G. Decerprit +2
The significant attenuation of the cosmic-ray flux above eV suggests that the observed high-energy spectrum is shaped by the so-called GZK effect. This interaction…
Correlation of the highest-energy cosmic rays with the positions of nearby active galactic nuclei
The Pierre Auger Collaboration
Data collected by the Pierre Auger Observatory provide evidence for anisotropy in the arrival directions of the cosmic rays with the highest energies, which are correlated with the…
Cosmogenic Neutrinos from the propagation of Ultra High Energy Nuclei
D. Allard, M. Ave, N. Busca +5
We calculate the flux of neutrinos generated by the propagation of ultra-high energy nuclei over cosmological distances. The propagation takes into account the interactions with co…
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…
