Prediction of cosmic ray signatures on Earth from nearby supernova explosions — •Jonathan Heil — Ruhr-University Bochum, Germany

Supernova remnants are among the most promising candidates for the production of a large component of the cosmic-ray flux at Earth. However, even more than 100 years after the detection of cosmic rays, the exact contribution to the luminosity of cosmic rays from SNRs is could not be fully quantified yet. In this contribution, we present a simulation performed with the CRPropa transport framework, in which particles are propagated from sources in the Galaxy to Earth for different source parameters like luminosity, activity time and position. The goal is to map the influence of nearby supernova remnants on the diffusive cosmic ray flux and to extend the simulated cosmic ray energy range to low energies. In this talk, the simulation setup will be presented together with first results.
