Search Sources of Cosmic Rays Ultrahigh Energy

TL;DR

This paper analyzes the arrival directions of ultrahigh energy cosmic rays, revealing anisotropy and correlations with pulsars near the Galaxy's Orion arm, suggesting potential sources.

Contribution

It presents new evidence of anisotropic arrival directions and correlations with pulsars, indicating possible origins of ultrahigh energy cosmic rays.

Findings

EAS with deficit muons are not isotropic

Majority of these EAS form doublets near the Galaxy's anticenter

Some EAS correlate with pulsars near the Orion arm

Abstract

The arrival directions of ultrahigh energy extensive air showers (EAS) by Yakutsk, AGASA and P. Auger data are considered. It is found that the arrival directions of EAS with a deficit muons by Yakutsk data are not isotropy. Majority of these EAS form doublets which have maximum at side anticenter of Galaxy. It is shown that some EAS by data of Yakutsk, AGASA, P.Auger correlate with pulsars. These pulsars are situated near Input and Output Local arm Galaxy Orion. The majority of these pulsars have a short period rotate around of their axes. The problem of cosmic ray origin is discussed.
