Search for Sources of Ultrahigh Energy Cosmic Rays

TL;DR

This paper investigates the origins of ultrahigh energy cosmic rays by analyzing their arrival directions and finds correlations with pulsars, suggesting pulsars as potential sources of these cosmic rays.

Contribution

It presents a comparative analysis of data from Yakutsk, AGASA, and P. Auger, revealing correlations between cosmic ray directions and pulsars, highlighting pulsars with short rotation periods as likely sources.

Findings

Correlations between EAS arrival directions and pulsars in Yakutsk and AGASA data.

Correlations between EAS arrival directions and pulsars in P. Auger data from the Local Arm of Orion.

Most correlated pulsars have shorter rotation periods than cataloged.

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 in the Yakutsk and AGASA data are correlated with pulsars from the side Input, and in the P. Auger data are correlated with pulsars from the Output of the Local Arm of Orion. It is shown that the majority of these pulsars have a short rotation period around their axes, than expected by the pulsar catalogue.
