Are Fast Radio Bursts Produced By Large Glitches Of Anomalous X-ray Pulsars?

TL;DR

This paper explores the hypothesis that fast radio bursts originate from large glitches in anomalous X-ray pulsars caused by star quakes and phase transitions, linking surface bursts to relativistic particle emissions.

Contribution

It proposes a novel model connecting pulsar glitches and surface bursts to the production of fast radio bursts through relativistic particle emissions.

Findings

FRBs may be produced by glitches in AXPs and SGRs.

Surface x-ray and gamma-ray bursts are detectable only from nearby galaxies.

Relativistic e+e- bunches emit coherent curvature radiation observable as FRBs.

Abstract

Star quakes and internal phase transitions within anomalous x-ray pulsars (AXPs) and soft $\gamma$-ray repeaters (SGRs) can produce mini contractions and pulsar glitches. Shocks break out from their surface following such contractions produce thermal x/$\gamma$-ray bursts. Highly relativistic dipolar $e^+e^-$ bunches launched from the pulsar polar caps emit fast radio bursts (FRBs) of narrowly beamed coherent curvature radiation, visible if they point in the direction of Earth. Although these surface x/$\gamma$-ray bursts are isotropic and are many orders of magnitude more energetic than the FRBs, they are detectable by the current all sky x-ray and $\gamma$-ray monitors only from our galaxy and very nearby galaxies.
