| Outline of Final Research Achievements |
High-energy cosmic rays are thought to be accelerated by shock waves associated with explosive events in the universe. In this study, we used a supercomputer to simulate the dynamics of relativistic (near light speed) shocks. Specifically, we found that electrons radiate intense electromagnetic waves regardless of the strength of the upstream magnetic field. The emitted electromagnetic waves interact with the upstream plasma and accelerate both ions and electrons. We conducted a survey of the upstream magnetic field strength and identified the most efficient electromagnetic radiation mechanism. This suggests that it can be applied to neutron star flares with strong magnetic fields.
