Regions of an excessive flux of cosmic rays according to data of the FIAN and MSU arrays

TL;DR

This paper identifies specific regions with an excess of cosmic ray flux across multiple datasets, indicating potential sources or phenomena related to cosmic ray origins.

Contribution

It presents a novel blind search for localized cosmic ray flux excesses using data from three different arrays, revealing consistent regions across datasets.

Findings

Multiple regions with significant flux excesses identified

Some regions are consistent across different datasets

Results suggest potential cosmic ray sources or anisotropies

Abstract

Results of a blind search for localized regions of an excessive flux of cosmic rays in the energy range from 50 TeV to 20 PeV with the data of the FIAN KLARA-Chronotron experiment, the EAS MSU array and the Prototype of the EAS-1000 array are presented. A number of regions with a significant excess of the registered flux over an expected isotropic background are found. Some of the regions are present in at least two of the data sets considered.
