Abstract
Three pairs of possibly correlated ultra-high-energy cosmic-ray events were reported by Hayashida et al. Three different numerical models are combined to study the propagation of the corresponding particles through both the intergalactic and Galactic magnetic fields. The spatial dependences of fields and galaxies are accounted for. The results suggest that the pairs are chance clusterings.Keywords
