Analysis reveals energy dependence of cosmic rays in relation to their extragalactic sources, suggesting limits on distance.
Assuming cosmic rays at ultra-high energies being of extragalactic origin we discuss propagation of cosmic iron nuclei with energies above 10 eV from their sources to the Galaxy. In extragalactic space cosmic nuclei interact with background emissions and inevitably fragment. We analyze the fraction of iron nuclei reaching the Earth and its energy dependence on distances from cosmic ray sources. It is obtained that energies of iron nuclei can be used to find restriction on the distances from their sources.
