Ultra-High Energy Cosmic Ray Study Results by Radio Emission Technique at Yakutsk Array

Аннотация

The Yakutsk array is designed to study cosmic rays at energy 10¹⁵–10²⁰ eV. The array detects charged particles, muons, Cherenkov light and radio emission. Radio-emission method is capable to study air shower physics independently of other shower components, including energy estimation of primary particle, longitudinal development of the particle cascade in the atmosphere (in the case of the Yakutsk array the depth of maximum development X_max). For the showers with energy E ⩾ 10¹⁹ eV arrival directions were tracked and reconstructed in galactic and equatorial coordinate system to search for cosmic ray sources with such energies.
