The recent discovery of a Galactic fast radio burst (FRB) associated with a hard X-ray burst from the soft gamma-ray repeater (SGR) J1935+2154 has established the magnetar origin of at least some FRBs. In this work, we study the statistical properties of soft gamma-ray/hard X-ray bursts from SGRs 1806–20 and J1935+2154 and of radio bursts from the repeating FRB 121102. For SGRs, we show that the probability density functions for the differences of fluences, fluxes, and durations at different…

HXMT identification of a non-thermal X-ray burst from SGR J1935+2154 and with FRB 200428

Fast radio bursts (FRBs) are short pulses observed in the radio band from cosmological distances1. One class of models invokes soft gamma-ray repeaters (SGRs), or magnetars, as the sources of FRBs2.

Statistical properties of magnetar bursts and FRB 121102

In this paper, we present statistics of soft gamma repeater (SGR) bursts from SGR J1550−5418, SGR 1806−20, and SGR 1900+14 by adding new bursts from Kırmızıbayrak et al. detected with the Rossi

HOW SOFT GAMMA REPEATERS MIGHT MAKE FAST RADIO BURSTS

There are several phenomenological similarities between soft gamma repeaters (SGRs) and fast radio bursts (FRBs), including duty factors, timescales, and repetition. The sudden release of magnetic

A peculiar hard X-ray counterpart of a Galactic fast radio burst

Fast radio bursts are bright, millisecond-scale radio flashes of yet unknown physical origin. Recently, their extragalactic nature has been demonstrated, and an increasing number of the sources have

An X-ray burst from a magnetar enlightening the mechanism of fast radio bursts

Fast radio bursts (FRBs) are short (millisecond) radio pulses originating from enigmatic sources at extragalactic distances so far lacking a detection in other energy bands. Magnetized neutron stars

A giant periodic flare from the soft γ-ray repeater SGR1900+14

Soft γ-ray repeaters are transient sources of high-energy photons; they emit sporadic and short (about 0.1 s) bursts of ‘soft’ γ-rays during periods of activity, which are often broken by long

Statistical Properties of SGR 1806–20 Bursts

The hypothesis that the energy source for soft gamma repeater bursts is crustquakes due to the evolving, strong magnetic field of the neutron star, rather than any accretion or nuclear power is supported.

BURST FLUENCE DISTRIBUTIONS OF SOFT GAMMA REPEATERS 1806−20 AND 1900+14 IN THE ROSSI X-RAY TIMING EXPLORER PCA ERA

We study the fluence distributions of over 3040 bursts from SGR 1806−20 and over 1963 bursts from SGR 1900+14 using the complete set of observations available from the Rossi X-Ray Timing

Statistical Properties of SGR 1900+14 Bursts

The analysis lends support to the hypothesis that the energy source for SGR bursts is internal to the neutron star and plausibly magnetic, and gives evidence for self-organized criticality in SGRs.

Scale-invariance in soft gamma repeaters

The statistical properties of the soft gamma repeater SGR J1550--5418 are investigated carefully. We find that the cumulative distributions of fluence, peak flux and duration can be well fitted by a
