Escape model for Galactic cosmic rays and an early extragalactic transition
Escape model for Galactic cosmic rays and an early extragalactic transition
We show that the cosmic ray (CR) knee can be entirely explained by energy-dependent CR leakage from the Milky Way, with an excellent fit to all existing data. We test this hypothesis calculating the trajectories of individual CRs in the Galactic magnetic field. We find that the CR escape time …
