Electron Acceleration during Macroscale Magnetic Reconnection

The first self-consistent simulations of electron acceleration during magnetic reconnection in a macroscale system are presented. Consistent with solar flare observations the spectra energetic electrons take form power-laws that extend more than two decades energy. drive mechanism for these nonthermal is Fermi reflection growing and merging flux ropes. A strong guide field found to suppress production by weakening mechanism. For weak total energy content dominates hot thermal even though their number density remains small. Our results benchmarked hard x-ray, radio extreme ultra-violet (EUV) X8.2-class on September 10, 2017.
