A beam of ultrahigh energy particles of the same magnetic rigidity

TL;DR

This paper reports the detection of three ultra-high-energy cosmic ray particles with similar magnetic rigidity, suggesting a common origin or acceleration process, based on observations from two different arrays.

Contribution

It presents evidence of a beam of particles with the same magnetic rigidity at energies above 30 EeV, indicating magnetic separation effects in their acceleration and propagation.

Findings

Three particles detected with energies above 30 EeV from the same sky region.

Particles exhibit similar magnetic rigidity despite differing energies.

Evidence suggests magnetic separation in acceleration and propagation processes.

Abstract

Two EAS arrays during a day have recorded 3 particles with energies above 30 EeV arriving from the same sky region. Two events were registered by the Yakutsk array and one - by the Telescope Array. Two Yakutsk events were estimated to be same energy and the Telescope Array shower's energy was almost 2 times higher. This indicates the same magnetic rigidity of all three particles, if the charge differs by a factor of 2. The relatively short sequence of all three events and their "monochromaticity" in rigidity can be due to the magnetic separation of particles in the acceleration process and propagation of the beam.
