Supercluster Magnetic Fields and Anisotropy of Cosmic Rays above 10**(19) eV
Abstract
We predict energy spectra and angular distributions of nucleons above 10**(19) eV that originate from sources distributed in the Local Supercluster, which is also supposed to contain a large scale magnetic field of strength between 0.05 and 0.5 micro Gauss. We show that this model can explain all present-day features of ultra-high energy cosmic rays, at least for field strengths close to 0.5 micro Gauss. The large-scale anisotropy and the clustering predicted by this scenario will allow strong discrimination against other models with next generation experiments.
