Particles Flux of Ultrahigh Energy from a Galactic Plane

TL;DR

This paper presents evidence of ultrahigh energy particles arriving preferentially from the galactic plane, using a new anisotropy detection method applied to extensive air shower data.

Contribution

It introduces a novel method for source search and anisotropy analysis of particle arrival directions in cosmic ray data.

Findings

Detected flux of ultrahigh energy particles from the galactic plane exceeding isotropic expectations by over 4σ and 5σ.

Proposed a new approach for analyzing anisotropy in extensive air shower data.

Confirmed the non-isotropic distribution of ultrahigh energy cosmic rays.

Abstract

Arrival directions of particles were analyzed according to the arrays of extensive air showers (EAS) data. A new method of sources search and anisotropy of arrival directions particles is suggested. There was found the particles flux of ultrahigh energy from the galactic plane that exceeds the expected number of particles in the case of isotropy more than 4\sigma and 5\sigma.
