Search of primary cosmic rays sources at 5x10**13 - 5x10**14 eV with Tien Shan CHRONOTRON - KLARA array

TL;DR

This study searches for cosmic ray sources using the Tien Shan CHRONOTRON-KLARA array by analyzing extensive air showers within 5x10^13 to 5x10^14 eV, identifying potential source directions through statistical deviations.

Contribution

It introduces a method of detecting cosmic ray sources by analyzing deviations in event counts in specific sky regions using a large dataset from the Tien Shan array.

Findings

Identification of directions with significant event excesses.

Comparison of detected directions with known astrophysical sources.

Validation of the method against other observational results.

Abstract

The primary cosmic ray sources are searched by means of CHRONOTRON - KLARA separate array of the P.N. Lebedev Physical Institute Tien Shan station. It was done on the base of 35 millions observed PCR extensive air showers from 5x10**13 to 5x10**14 eV energies. The data analysis was carried on the method of the direct selection of local areas in equatorial coordinates where the deviation of event numbers exceeded the definite value from normal Gaussian standard. These directions are compared with other arrays observed results and with coordinates of astrophysical sources.
