Ultrahigh energy cosmic rays from a nearby extragalactic source in the diffusive regime
Original language description
We study the effects that the diffusion of cosmic rays in the magnetic field of the Local Supercluster can have on the spectrum of a nearby extragalactic source at ultrahigh energies. We find that the strong enhancement of the flux below the energy at which the transition between the diffusive and quasirectilinear regimes takes place, as well as the suppression at lower energies associated with a finite source age, can help to explain the observed features of the cosmic-ray spectrum and composition. Scenarios are discussed in which a nearby extragalactic source with mixed composition and a rigidity-dependent spectrum accounts for most of the observed cosmic rays at energies above a few EeV, while the rest of the extragalactic sources lead to a diffuse flux that dominates at lower energies and down to similar to 0.1 EeV.
