TLDR
A millisecond-duration radio burst from the Galactic magnetar SGR-1935+2154 with a fluence of 1.5 ± 0.3 megajansky milliseconds was detected by the STARE2 radio array in the 1,281-1,468 megahertz band.Abstract:
Since their discovery in 20071, much effort has been devoted to uncovering the sources of the extragalactic, millisecond-duration fast radio bursts (FRBs)2. A class of neutron stars known as magnetars is a leading candidate source of FRBs3,4. Magnetars have surface magnetic fields in excess of 1014 gauss, the decay of which powers a range of high-energy phenomena5. Here we report observations of a millisecond-duration radio burst from the Galactic magnetar SGR 1935+2154, with a fluence of 1.5 ± 0.3 megajansky milliseconds. This event, FRB 200428 (ST 200428A), was detected on 28 April 2020 by the STARE2 radio array6 in the 1,281–1,468 megahertz band. The isotropic-equivalent energy released in FRB 200428 is 4 × 103 times greater than that of any radio pulse from the Crab pulsar—previously the source of the brightest Galactic radio bursts observed on similar timescales7. FRB 200428 is just 30 times less energetic than the weakest extragalactic FRB observed so far8, and is drawn from the same population as the observed FRB sample. The coincidence of FRB 200428 with an X-ray burst9–11 favours emission models that describe synchrotron masers or electromagnetic pulses powered by magnetar bursts and giant flares3,4,12,13. The discovery of FRB 200428 implies that active magnetars such as SGR 1935+2154 can produce FRBs at extragalactic distances. Observations of the fast radio burst FRB 200428 coinciding with X-rays from the Galactic magnetar SGR 1935+2154 indicate that active magnetars can produce fast radio bursts at extragalactic distances.read more

Synthesising the repeating FRB population using frbpoppy
TL;DR: All FRBs originate from a single and mostly uniform population of varying repeaters, and it is concluded that the luminosity function cannot be steep, and there must be minor differences in physical or behaviour parameters that correlate with the repetition rate.

TL;DR: In this article , a family of model invoking coherent inverse Compton scattering (ICS) of bunched particles that may operate within or just outside of the magnetosphere of a flaring magnetar was proposed.

Coherent Emission in Pulsars, Magnetars, and Fast Radio Bursts: Reconnection-driven Free Electron Laser
TL;DR: In this paper, a model of the generation of coherent radio emission in the Crab pulsar, magnetars and Fast Radio Bursts (FRBs) was developed, where emission is produced by a reconnection-generated beam of particles via a variant of Free Electron Laser (FEL) mechanism, operating in a weakly-turbulent, guide-field dominated plasma.

Repeating fast radio bursts caused by small bodies orbiting a pulsar or a magnetar
TL;DR: In this paper, it was shown that the Lorimer burst can be explained by small size pulsar companions (1 to 10 km) between 0.03 and 1 AU from a highly magnetized millisecond pulsar.
