Neutrinos from Auger Sources
Abstract
The Pierre Auger observatory has presented evidence that the arrival directions of cosmic rays with energies in excess of 6x107 TeV may be correlated with nearby active galactic nuclei (AGN). In this context we revisit a suggestion based on gamma ray observations that nearby Fanaroff-Riley I galaxies such as Cen A and M87 are the sources of the local cosmic rays. We compute the accompanying neutrino flux and find a flux within reach of second-generation kilometer-scale neutrino telescopes.
