Abstract
A magnetosonic shock wave propagating obliquely to an external magnetic field can trap and accelerate electrons to ultrarelativistic energies. These electrons can excite electromagnetic fluctuations along the shock front. The effects of the electromagnetic fluctuations on electron motion are investigated by two-dimensional electromagnetic particle simulations and test particle calculations in which equation of motion of electrons in the electromagnetic fields averaged along the shock front is computed. Comparisons of the two results verify that the electromagnetic fluctuations along the shock front can cause detrapping of energetic electrons from the main pulse and their subsequent acceleration to higher energies. It is also demonstrated that as the external magnetic field strengthens, the electromagnetic fluctuations along the shock front grow to larger amplitudes, and the detrapping and subsequent acceleration of electrons enhance.
