Are fast radio bursts produced by large glitches of anomalous x-ray pulsars?

Abstract

Phase transitions within anomalous X-ray pulsars (AXPs) and soft γ-ray repeaters (SGRs) can lead to mini contractions. Such contractions produce pulsar gliches and shock break outs from their surface accompanied by thermal X/γ -ray emission. Highly relativistic dipolar e+e− bunches launched from the pulsar polar caps emit fast radio bursts (FRBs) of narrowly beamed coherent curvature radiation, visible from cosmic distances if they point in the direction of Earth. Although the associated bursts of surface X/γ -rays are nearly isotropic, and many orders of magnitude more energetic than the FRBs, they are detectable by the current all sky X-ray and γ-ray monitors only from our galaxy and nearby galaxies.
