Anisotropies and clustering of extragalactic cosmic rays
arXiv:astro-ph/0610862 · doi:10.1016/j.nuclphysbps.2006.11.039
Abstract
Deviations from isotropy have been a key tool to identify the sources and the primary type of cosmic rays (CRs) at low energies. We argue that anisotropies due to blind regions induced by the Galactic magnetic field, the cosmological Compton-Getting effect, medium-scale anisotropies reflecting the large-scale distribution of CR sources and the small-scale clustering of the CR arrival directions at the highest energies may play the same role for extragalactic CRs.
