Beam of Ultrarelativistic Particles and Cherenkov Resonance

Abstract

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.
