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…

The GZK horizon and constraints on the cosmic ray source spectrum from observations in the GZK regime
M. Kachelriess, E. Parizot, D. V. Semikoz
We discuss the GZK horizon of protons and present a method to constrain the injection spectrum of ultrahigh energy cosmic rays (UHECRs) from supposedly identified extragalactic sou…

Constraints on top-down models for the origin of UHECRs from the Pierre Auger Observatory data
D. V. Semikoz
Taking into account the Pierre Auger Observatory limits on the photon fraction among the highest energy cosmic rays, we show that the models based on the decay of super-heavy dark…
