“…Some theoretical models based on magnetars have been proposed (Kulkarni et al 2014;Lyubarsky 2014;Katz 2016;Murase et al 2016;Beloborodov 2020;Metzger et al 2019;Wang et al 2020). Interestingly, the statistical properties of the repeating bursts are consistent with Galactic magnetar bursts (Wang & Yu 2017;Wadiasingh & Timokhin 2019;Cheng et al 2020;Zhang et al 2021;Wei et al 2021;Sang & Lin 2022).…”

Fast radio bursts (FRBs) are pulsed radio signals with a duration of milliseconds and a large dispersion measure. Recent observations indicate that FRB 180916 and FRB 121102 show periodic activities. Some theoretical models have been proposed to explain periodic FRBs, and here we test these using corresponding X-ray and γ-ray observations. We find that the orbital periodic model, the free precession model, the radiation-driven precession model, the fall-back disk precession model where eccentricity is due to the internal magnetic field, and the rotation periodic model are not consistent with observations. The geodetic precession model is the most likely periodic model for FRB 180916. We also propose methods to test the periodic models with yet-to-be-obtained observational data in the future.

Precursors provide important clues to the nature of gamma-ray burst (GRB) central engines and can be used to contain GRB physical processes. In this Letter, we study the self-organized criticality in precursors of long GRBs in the third Swift/Burst Alert Telescope catalog. We investigate the differential and cumulative size distributions of 100 precursors, including peak flux, duration, rise time, decay time, and quiescent time with the Markov Chain Monte Carlo technique. It is found that all of the distributions can be well described by power-law models and understood within the physical framework of a self-organized criticality system. In addition, we inspect the cumulative distribution functions of the size differences with a q-Gaussian function. The scale-invariance structures of precursors further strengthen our findings. Particularly, similar analyses are made in 127 main bursts. The results show that both precursors and main bursts can be attributed to a self-organized criticality system with the spatial dimension S = 3 and driven by a similar magnetically dominated process.

“…Statistical analysis of FRB 121102 shows that the burst energies and waiting times follow the power-law distribution [17][18][19], hinting that the explosion of repeating FRBs may be a self-organized criticality process. Further analysis shows that the bursts of FRB 121102 can be more well fitted by the bent power-law and are scale-invariant [20], implying that there are some similarities between FRBs and soft gamma repeaters (SGRs) [21,22]. As the FAST telescope extensively increases the bursts from FRB 121102, a bimodal burst energy distribution is found [16].…”

The application of fast radio bursts (FRBs) as probes to investigate astrophysics and cosmology requires the proper modelling of the dispersion measures of Milky Way (DMMW) and host galaxy (DM host ). DMMW can be estimated using the Milky Way electron models, such as NE2001 model and YMW16 model. However, DM host is hard to model due to limited information on the local environment of FRBs. In this paper, using 17 well-localized FRBs, we search for the possible correlations between DM host and the properties of host galaxies, such as the redshift, the stellar mass, the star-formation rate, the age of galaxy, the offset of FRB site from galactic center, and the half-light radius. We find no strong correlation between DM host and any of the host property. Assuming that DM host is a constant for all host galaxies, we constrain the fraction of baryon mass in the intergalactic medium today to be fIGM,0 = 0.78 +0.15 −0.19 . If we model DM host as a log-normal distribution, however, we obtain a larger value, fIGM,0 = 0.83 +0.12 −0.17 . Based on the limited number of FRBs, no strong evidence for the redshift evolution of fIGM is found.
