Superbubble Origin of Cosmic Rays

TL;DR

This paper discusses the discovery that superbubbles are the primary origin of cosmic rays, summarizing the journey through astronomical observations and measurements over the past century.

Contribution

It provides a concise overview of the evidence linking superbubbles to cosmic ray production, clarifying their role in cosmic ray origins.

Findings

Superbubbles are confirmed as the main sources of cosmic rays.

Cosmic ray measurements align with superbubble acceleration models.

Abstract

After a hundred years of searching for the origin of cosmic rays, where and how they are made has finally become clear. Here we briefly trace that odyssey through both astronomical observations and cosmic ray measurements.
