High energy astronomical objects such as the active galactic nuclei and radio galaxies were searched as a possible origin of such EHECRs, but none were found in the arrival direction of these events within 100 Mpc of our galaxy3. More distant origins may be considered, but only if a special mechanism to allow a longer propagation of EHECRs to take place, for example the violation of special relativity4 or the EHE neutrinos as the carrier of such energy.
