Paper:... study suggests that those particles come from the filaments of galaxies connected to the Virgo Cluster, in the sky around the hotspot and their locations in the sky are correlated to hotspot events with a high statistical significance.- Scientists shed new light on mystery origin of ultra-high-energy cosmic ray hotspot
Cosmic Ray Composition:We here report the presence of filaments of galaxies, connected to the Virgo Cluster, on the sky around the hotspot, and a statistically significant correlation between hotspot events and the filaments. - Filaments of Galaxies as a Clue to the Origin of Ultra-High-Energy Cosmic Rays: Jihyun Kim et al
Air Showers:Almost 90% of the cosmic rays which strike the Earth's atmosphere are protons (hydrogen nuclei) and about 9% are alpha particles. Electrons amount to about 1% according to Chaisson & McMillan. - Hyperphysics
"Air Showers": Cosmic Rays then interact to induce an avalanche (or "atmospheric breakdown") of particles including nuclear, muonic, and an "electromagnetic component". That is pretty interesting.
With this in mind, and considering the Sun, my question is: Are expectations that one relatively local electric current filament to "power the sun" unrealistic?
