One of the fundamental problems of astrophysics is the study of sources and mechanisms for the formation of high and ultrahigh energy cosmic rays. It is assumed that primary cosmic rays in the energy range 10^16-10^19 eV are generated by both galactic and (at higher energies) extragalactic sources . One of the ways to detect high-energy cosmic rays is to fix the radiation generated by EAS (Extensive Atmospheric Showers) from the penetration of cosmic ray particles into the Earth's atmosphere.
It is known that the maximum radiation from EAS falls at frequencies from 100 to 110 MHz, at which the BSA FIAN operates. The paper presents the methodology and results of the analysis of hundreds of thousands of impulse signals with zero dispersion delay in many beams of the BSA diagram for 2012-2020 at once. An analysis of such signals and their separation into different fractions was carried out. Analysis of the data showed that a very significant part of these data (up to tens of percent of the entire array), apparently, is generated by EAS.
This study was carried out using the supercomputer complex of the National Research University Higher School of Economics.
