Abstract: (arXiv)
The cosmic ray spectrum at , reported by the Fly's Eye and the AGASA experiments, is shown to be consistent with a cosmological distribution of sources of protons, with a power law generation spectrum and energy production rate of . The two events measured above are not inconsistent with this model. Verifying the existence of a ``black-body cutoff'', currently observed with low significance, would require observation-years with existing experiments, but only year with the proposed detectors. For a cosmological source distribution, no anisotropy is expected in the angular distribution of events with energies up to .- cosmic radiation: primary
