Signatures of Pulsar Polar-Cap Emission at the High-Energy Spectral Cut-off
J. Dyks, B. Rudak
Abstract
We address four unique signatures in pulsar gamma-ray radiation as predicted by polar-cap models. These signatures are expected to be present nearby the spectral high-energy cutoff at around several GeV. Their magnitude and, therefore, their observability depends strongly on the orientational factors, the rotation, as well as on the details of the polar cap structure. These strong predictions are likely to be verified by the NASA's future gamma-ray mission GLAST.
