Abstract
We argue that the data published by the Pierre Auger Collaboration
[9gorb-PA] disfavor at 99%
confidence level their hypothesis that most of the highest-energy
cosmic rays are protons from nearby astrophysical sources, either
Active Galactic Nuclei or other objects with a similar spatial
distribution.
