Beam of Ultrarelativistic Particles and Cherenkov Resonance

Earlier, we reported on registration of three sequential events with energies greater than 1019 eV with two installations of EAS (Yakutsk and Telescope Arrays) for one day. Here we take into account that a moving relativistic source creates a particle beam due to the Cherenkov effect. In this case, with a certain orientation of the direction of movement of the source relative to the observer and direction of the interstellar magnetic field, there is a mechanism that allows to explain the observed sequence of the recorded events.
