The energy spectrum of cosmic rays extends over many orders of magnitude with a steep suppression of the flux at the highest energies. The energy spectrum of ultra-high energy cosmic rays (UHECR) is measured with great precision by the Pierre Auger Observatory and Telescope Array. However, the two measured spectra show different slopes of the suppression of the spectrum at the highest energies. This disagreement can be caused by the ability of these two experiments to see different parts of the sky and, therefore, in principle, different sources of UHECR as well. In our study, we investigate the possibility that the energy spectrum measured by the Pierre Auger Observatory at energies above log10(E/eV)≥19.5 could be explained by a dominant single strong source.
