“…In addition, the same power-law distributions of X-ray flares or bursts have been found in other systems, for example, some black hole binary systems (Wang et al 2015;Yan et al 2018), type I X-ray bursts originated from X-ray binary systems with low-mass (Wang et al 2017), some repeating FRBs (Wang et al 2017;Zhang et al 2020;Wang et al 2023), and soft gamma repeaters (e.g., Cheng et al 1996;Göǧüs et al 1999Göǧüs et al , 2000Cheng et al 2020). The similar distributions for parameters of X-ray flares from supergiant fast X-ray transients are also reported by Sidoli et al (2016) and Zhang et al (2022).…”

“…The SOC features have been found in FRB 121 102 (e.g., Cheng et al 2020;Zhang et al 2021). Recently, Wang et al (2023) studied the frequency distributions of burst energy and waiting time of the two repeating FRBs 20121102A and 20201124. According to the bimodal distributions of the waiting time, the bursts are divided into long and short parts.…”

As one class of the most important objects in the universe, magnetars can produce a lot of different frequency bursts including X-ray bursts. In Cai et al., 75 X-ray bursts produced by magnetar SGR J1935+2154 during an active period in 2020 are published, including the duration and net photon counts of each burst, and waiting time based on the trigger time difference. In this paper, we utilize the power-law model, dN ( x ) / dx ∝ ( x + x 0 ) − α x , to fit the cumulative distributions of these parameters. It can be found that all the cumulative distributions can be well fitted, which can be interpreted by a self-organizing criticality theory. Furthermore, we check whether this phenomenon still exists in different energy bands and find that there is no obvious evolution. These findings further confirm that the X-ray bursts from magnetars are likely to be generated by some self-organizing critical process, which can be explained by a possible magnetic reconnection scenario in magnetars.

“…The statistical distributions of glitch sizes (Δν) and times between successive glitches (waiting times) for some individual pulsars are power-law forms (Morley & Garcia-Pelayo 1993;Melatos et al 2008;Carlin & Melatos 2021). Power-law distributions of energy and waiting time are also found in some repeating FRBs (Wang & Yu 2017;Katz 2018;Gourdji et al 2019;Cheng et al 2020;Cruces et al 2021;Li et al 2021b;Zhang et al 2021;Hewitt et al 2022;Jahns et al 2023;Wang et al 2023). Inspired by the associations between the glitch/antiglitch and FRB-like bursts of SGR J1935+2154 and the statistical similarities between pulsar glitches and repeating FRBs, here we investigate whether pulsar glitches have similar scaleinvariant behavior.…”

The recent discoveries of a remarkable glitch/antiglitch accompanied by fast radio burst (FRB)-like bursts from the Galactic magnetar SGR J1935+2154 have revealed the physical connection between the two. In this work, we study the statistical properties of radio bursts from the hyperactive repeating source FRB 20201124A and of glitches from the pulsar PSR B1737–30. For FRB 20201124A, we confirm that the probability density functions of fluctuations of energy, peak flux, duration, and waiting time well follow the Tsallis q-Gaussian distribution. The derived q values from q-Gaussian distribution keep approximately steady for different temporal interval scales, which indicates that there is a common scale-invariant structure in repeating FRBs. Similar scale-invariant properties can be found in PSR B1737–30's glitches, implying an underlying association between the origins of repeating FRBs and pulsar glitches. These statistical features can be well understood within the same physical framework of self-organized criticality systems.

“…In many ways, the quest to identify the sources of FRBs followed the same path as GRBs: searches for repetition, counterparts in other wavelengths and messengers, and identification and characterization of host galaxies. The searches for repetition have led to the phenomenological classes of nonrepeating and repeating FRBs, the latter of which show similarities and are thought to be related to SGR short bursts (Scholz et al 2016;Wadiasingh & Timokhin 2019;Wadiasingh et al 2020;Oostrum et al 2020;Wei et al 2021;Zhang et al 2021;Wang et al 2023;Lander 2023). However, radio observations of the dispersion measure, polarization, and rotation provide additional and unique diagnostic information on the origin of these sources .…”

The Interplanetary Network (IPN) is a detection, localization and alert system that utilizes the arrival time of transient signals in gamma-ray detectors on spacecraft separated by planetary baselines to geometrically locate the origin of these transients. Due to the changing astrophysical landscape and the new emphasis on time domain and multimessenger astrophysics (TDAMM) from the Pathways to Discovery in Astronomy and Astrophysics for the 2020s, this Gamma-ray Transient Network Science Analysis Group was tasked to understand the role of the IPN and high-energy monitors in this new era. The charge includes describing the science made possible with these facilities, tracing the corresponding requirements and capabilities, and highlighting where improved operations of existing instruments and the IPN would enhance TDAMM science. While this study considers the full multiwavelength and multimessenger context, the findings are specific to space-based high-energy monitors. These facilities are important both for full characterization of these transients as well as facilitating follow-up observations through discovery and localization. The full document reports the history of this field in Section 1, followed by our detailed analyses and findings in some 68 pages, providing a holistic overview of the role of the IPN and high-energy monitors in the coming decades.We here summarize our core conclusions. Scientific breakthroughs which require capable high-energy monitors are fully detailed in Section 2. Specific questions of interest include: unique example of NASA's Transform to Open Science initiative. Adding the numerous gamma-ray smallsats to the collaboration would allow for greater inclusion of the international community, ensure maximum gain of their data, act to facilitate inclusion of private data towards productive TDAMM results, and allow the United States to support the developing space capabilities in other countries.We identify a number of specific actions that could be taken by NASA to increase the TDAMM return of current, forthcoming, and future facilities, discussed in Section 4. These include:• Enhanced space-based communications: Providing additional communication contacts for gamma-ray burst monitors will lead to faster retrieval of data and data of higher quality (e.g. high resolution time-tagged event data). The immediate allocation of additional contacts for the Neil Gehrels Swift Observatory is important to discovery in the on-going gravitational-wave observing run (the capability was requested in the latest Senior Review round but not mentioned in the report). Similar improvements can be made to forthcoming Astrophysics missions like StarBurst and the Compton Spectrometer and Imager (COSI). This finding also applies to assets in NASA Planetary and Heliophysics, as well as missions led by other space agencies, where additional or more frequent contacts would boost the scientific return of the IPN and other TDAMM facilities. This provides an avenue for a TDAMM program built with international partn...
