The Pulsar Gamma-Ray Emission from High-resolution Dissipative Magnetospheres

The pulsar light curves and energy spectra are explored in dissipative magnetospheres with the Aristotelian electrodynamics (AE), where particle acceleration is fully balanced radiation reaction. AE non-zero pair multiplicity computed by a pseudo-spectral method co-moving frame. region near current sheet outside LC accurately captured high-resolution simulation. test trajectory including influence of both consistent accelerating electric field Our results can generally reproduce double-peak GeV cut-off agreement Fermi observations for $\kappa\gtrsim1$.
