Millisecond extragalactic radio bursts as magnetar flares

TL;DR

This paper supports the hypothesis that millisecond extragalactic radio bursts are related to magnetar flares, providing observational evidence and connecting recent discoveries to magnetar activity.

Contribution

It links observed millisecond radio bursts to magnetar hyperflares, strengthening the magnetar burst hypothesis with recent observational data.

Findings

Millisecond extragalactic radio bursts align with magnetar hyperflare properties.

Some bursts from M31 may be related to weaker magnetar bursts.

Supports magnetar origin hypothesis for fast radio bursts.

Abstract

Properties of the population of millisecond extragalactic radio bursts discovered by Thornton et al. (2013) are in good correspondence with the hypothesis that such events are related to hyperflares of magnetars, as was proposed by us after the first observation of an extragalactic millisecond radio burst by Lorimer et al. (2007). We also point that some of multiple millisecond radio bursts from M31 discovered by Rubio-Herrera et al. (2013) also can be related to weaker magnetar bursts.
