A revamped understanding of Cosmic Rays and Gamma-Ray Bursts

Year: 2025

Type: article

Abstract: Interesting data on Gamma Ray Burts (GRBs) and Cosmic Rays (CRs) have recently been made public. GRB221009A has a record “peak energy”. The CR electron spectrum has been measured to unprecedented high energies and exhibits a “knee” akin to the ones in all-particle or individual-element CR nuclei. IceCube has not seen high-energy neutrinos associated with GRBs. AMS has published a CR positron spectrum conducive to much speculation. We examine these data in the light of the “CannonBall Model” of GRBs and CRs, in which they are intimately related and which they do strongly validate.
