The meaning of the UHECR Hot Spots: A Light Nuclei Nearby Astronomy

TL;DR

This paper reviews UHECR events and supports a model where light nuclei like He, Be, and B explain observed patterns, including the absence of Virgo and the M82 source, with multiple potential sources identified.

Contribution

It confirms and updates a model suggesting UHECR are primarily light nuclei, explaining specific observational features and identifying multiple candidate sources.

Findings

UHECR are mainly light nuclei such as He, Be, B.

Virgo absence is explained by light nuclei composition.

M82 is confirmed as a primary source for the North TA Hot Spot.

Abstract

In this paper we review all the up-to-date Ultra High Energy Cosmic Rays (UHECR) events reported by AUGER, by Telescope Array (TA) and by AGASA in common coordinate maps. We also confirm our earliest (2008-2013) model, where UHECR are mostly made by light nuclei (namely He, Be, B), which explains the Virgo absence and confirms M82 as the main source for North TA Hot Spot. Many more sources, such as NGC253 and several galactic ones, are possible candidates for most of the 376 UHECR events. Several correlated map, already considered in recent years, are then reported to show all the events, with their statistical correlation values.
