| Outline of Final Research Achievements |
The code we built was used to simulate binary neutron star mergers endowed with magnetic fields. We observed the formation of an organized magnetic field structure, which may be the place where particles are accelerated and subsequently produce gamma rays. Satisfactory simulations of the accelerated particles themselves have not been performed yet, and will be the focus of the continuation of this research. We found that the organized magnetic field structure appears rather independently of the adopted equation of state, mass ratio, and initial magnetic field orientation.
