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…
Pierre Auger Data, Photons, and Top-Down Cosmic Ray Models
Nicolas Busca, Dan Hooper, Edward W. Kolb
We consider the ultra-high energy cosmic ray (UHECR) spectrum as measured by the Pierre Auger Observatory. Top-down models for the origin of UHECRs predict an increasing photon com…
Observing muon decays in water Cherenkov detectors at the Pierre Auger Observatory
P. Allison, F. Arneodo, X. Bertou +9
Muons decaying in the water volume of a Cherenkov detector of the Pierre Auger Observatory provide a useful calibration point at low energy. Using the digitized waveform continuous…
Cosmogenic Neutrinos from Ultra-High Energy Nuclei
Maximo Ave, N. Busca, A. V. Olinto +2
We calculate the flux of neutrinos generated by the propagation of ultra-high energy iron over cosmological distances and show that even if ultra-high energy cosmic rays are compos…
