Contribution to the local cosmic-ray flux from the Geminga supernova
P. A. Johnson
Abstract
The contribution to the local cosmic-ray flux from the Geminga supernova is calculated assuming shock acceleration to 1014 eV in a remnant which was formed several 105 years ago along with the Geminga pulsar. The particles are propagated to Earth using a simple diffusion model. In the region below the knee in the spectrum, it is found the supernova may contribute 10% of the local cosmic-ray flux, assuming plausible explosion parameters. The contribution to the amplitude of the anisotropy is not in conflict with the data in this energy region.
