Abstract: (Elsevier)
Results from the High Resolution Fly's Eye (HiRes) on the observation of the Greissen-Zatsepin-Kuzmin cutoff in the cosmic ray spectrum are presented. We observe a cutoff consistent with the GZK predictions with a five sigma significance. The natu re of the cosmic ray composition near the GZK cutoff is also discussed as well as possible correlations of the highest energy cosmic rays with AGNs in the Northern sky.References(0)
