Abstract

Possibility of generation of ultra high energy cosmic rays (UHECRs) by different classes of astrophysical objects, especially by radio galaxies and BL Lacertae (BL Lacs), is investigated. Noticeable correlation between arrival directions of UHECRs and distribution of brightest radiogalaxies is revealed. Meantime, a significant correlation is absent for BL Lacs.
