Anisotropy of ultra-high-energy cosmic rays in the Galaxy
Abstract
The propagation of ultra-high-energy cosmic rays (10^18-10^19 eV per nucleon) is investigated on the basis of recent information on regular and chaotic magnetic fields in the Galactic corona and disk. Calculations show that the observed anisotropy can be explained by models in which the ultra-high-energy cosmic rays originate in the Galaxy if the cosmic-ray sources uniformly fill the volume of the Galactic corona. The role of chaotic magnetic fields in the dynamics of particles with the energies considered is negligible.
