Identification of extragalactic cosmic-ray sources using data from various detection facilities

摘要

Showers with energies E > 3.2 * 10~(19) eV and E >= 10~(20) eV detected at the AGASA (Akeno, Japan), Haverah Park, and Yakutsk arrays are investigated. The question of how the identification of sources depends on the error in determining the shower arrival directions is analyzed. Confirmation is obtained for the conclusion in the author's earlier work, that the principal sources of shower-driven particles are Seyfert galaxies with red shifts z <= 0.0092, which are weak emitters in the x-ray and radio ranges.
