Reacceleration of Galactic Cosmic Rays Beyond the Knee at the Termination Shock of a Cosmic-Ray-Driven Galactic Wind

Kavli Affiliate: Roger Blandford | First 5 Authors: Payel Mukhopadhyay, Enrico Peretti, Noemie Globus, Paul Simeon, Roger Blandford | Summary: The origin of cosmic rays above the knee in the spectrum is an unsolved problem. We present a wind model in which interstellar gas flows along a non-rotating, expanding flux tube with a changing speed […]
