- Cosmic Ray Puzzle Solved Increased estimates of extragalactic magnetic fields may explain why possible HE CR sources, like AGN M87, do not align with observed CR directions.
- Nuclei Cooperate to Produce Single Particle Ultrahigh energy photons striking matter can transform into rho mesons through an interaction that involves many nuclei simultaneously, a phenomenon that may affect the detection signatures of high-energy particles from space.
