| 内容記述 | We completed a successful 14-year observation of the Akeno Giant Air Shower Array (AGASA). We observed about 1000 extremely highest energy cosmic rays (EHECRs) above 1019 eV including eleven events above 10^20 eV. The AGASA data indicate that the cosmic ray spectrum extends well beyond the predicted Greisen-Zatsepin-Kuz'min cutoff. In the arrival direction distribution of EHECRs, clusters of events are found which suggest the presence of the extragalactic EHECR point sources. The composition of EHECRs is consistent with light hadrons around 1019 eV, and no gamma-ray dominance has been observed. | |||||
