In this article, the authors summarize the basic physics of FRBs and discuss the current research progress in this area, including the observational property, propagation effect, population study, radiation mechanism, source model, and application in cosmology.Abstract:
In 2007, a very bright radio pulse was identified in the archival data of the Parkes Telescope in Australia, marking the beginning of a new research branch in astrophysics. In 2013, this kind of millisecond bursts with extremely high brightness temperature takes a unified name, fast radio burst (FRB). Over the first few years, FRBs seemed very mysterious because the sample of known events was limited. With the improvement of instruments over the last five years, hundreds of new FRBs have been discovered. The field is now undergoing a revolution and understanding of FRB has rapidly increased as new observational data increasingly accumulate. In this review, we will summarize the basic physics of FRBs and discuss the current research progress in this area. We have tried to cover a wide range of FRB topics, including the observational property, propagation effect, population study, radiation mechanism, source model, and application in cosmology. A framework based on the latest observational facts is now under construction. In the near future, this exciting field is expected to make significant breakthroughs.read more

Periodic Activities of Repeating Fast Radio Bursts from Be/X-ray Binary Systems
TL;DR: In this article, the authors proposed that a Be/X-ray binary (BeXRB) system composed of a neutron star (NS) and a Be star with a circumstellar disk, might be the source of a repeating fast radio burst with periodic activities, and apply this model to explain the activity window of FRB 180916B.

Dark photon dark matter and fast radio bursts
TL;DR: In this paper, the authors investigated the effect of light-dark photons (DP) on the time delay caused by fast radio bursts (FRBs) in the intergalactic medium.
Journal ArticleDOI
On the geometry and environment of repeating FRBs
TL;DR: In this paper, a geometrical explanation for periodically and non-periodically repeating fast radio bursts (FRBs) under neutron star (NS)-companion systems was proposed, within which the interaction between the NS and companion can trigger FRBs.

Dual-component plasma lens models
Adam Rogers,Xinzhong Er +1 more
TL;DR: In this article, the authors generalize individual plasma lens models to produce dual component lenses, which can both magnify and dim the appearance of background sources as a function of frequency.

Curvature-drift instability fails to generate pulsar radio emission
TL;DR: In this paper, the curvature-drift instability has been considered as a viable mechanism for pulsar radio emission, but it was shown that even though the waves could be amplified, the amplification factor remains very close to unity; therefore, this mechanism is unable to generate high brightness temperature emission from initial weak fluctuations.
