Fast radio bursts (FRBs) are cosmological radio transients with an unclear generation mechanism. Known characteristics such as their luminosity, duration, spectrum, and repetition rate, etc., suggest that FRBs are powerful coherent radio signals at GHz frequencies, but the status of FRBs near the source remains unknown. As an extreme astronomical event, FRBs should be accompanied by energy-comparable or even more powerful X/γ-ray counterparts. Here, particle-in-cell simulations of ultrastrong… 



The physical mechanisms of fast radio bursts.

The recent detection of a Galactic fast radio burst in association with a soft gamma-ray repeater suggests that magnetar engines can produce at least some, and probably all, fast radio bursts.

Fast radio bursts as synchrotron maser emission from decelerating relativistic blast waves

Fast radio bursts (FRBs) can arise from synchrotron maser emission at ultrarelativistic magnetized shocks, such as produced by flare ejecta from young magnetars. We combine particle-in-cell

On the Origin of Fast Radio Bursts (FRBs)

We derive stringent constraints on the persistent source associated with FRB 121102: size , age year, energy erg, characteristic electron energy the radiating plasma is confined by a cold plasma of

Fast radio burst source properties and curvature radiation model

We use the observed properties of fast radio bursts (FRBs) and a number of general physical considerations to provide a broad-brush model for the physical properties of FRB sources and the radiation

On the radiation mechanism of repeating fast radio bursts

Recent observations show that fast radio bursts (FRBs) are energetic but probably non-catastrophic events occurring at cosmological distances. The properties of their progenitors are largely unknown

No pulsed radio emission during a bursting phase of a Galactic magnetar.

The results suggest that FRB-SGR burst associations are rare, and it is possible that the physical conditions required to achieve coherent radiation in SGR bursts are difficult to satisfy, and that only under extreme conditions could an FRB be associated with an SGR burst.

A fast radio burst associated with a Galactic magnetar.

The discovery of FRB 200428 implies that active magnetars such as SGR 1935+2154 can produce FRBs at extragalactic distances, and favours emission models that describe synchrotron masers or electromagnetic pulses powered by magnetar bursts and giant flares.

A bright millisecond-duration radio burst from a Galactic magnetar.

The detection of an extremely intense radio burst from the Galactic magnetar SGR 1935+2154 using the Canadian Hydrogen Intensity Mapping Experiment (CHIME) FRB project implies a burst energy at 400 to 800 megahertz of approximately 3 × 1034 erg, which is three orders of magnitude higher than the burst energy of any radio-emitting magnetar detected thus far.

Can a Strong Radio Burst Escape the Magnetosphere of a Magnetar?

We examine the possibility that fast radio bursts (FRBs) are emitted inside the magnetosphere of a magnetar. On its way out, the radio wave must interact with a low-density e ± plasma in the outer

A Population of Fast Radio Bursts at Cosmological Distances

The detection of four nonrepeating radio transient events with millisecond duration in data from the 64-meter Parkes radio telescope in Australia indicates that these radio bursts had their origin outside the authors' galaxy, but it is not possible to tell what caused them.
