“…Finally, if the claimed ≈251 days periodic windowed behavior in the times of burst detections for SGR 1935 [238] and the possible 398.20 ± 25.45 days periodicity found in the high-energy bursts from SGR 1806-20 [239] will be confirmed, then the connection between magnetar short bursts and FRBs would be further strengthen.…”

The origin and phenomenology of the Fast Radio Burst (FRB) remains unknown despite more than a decade of efforts. Though several models have been proposed to explain the observed data, none is able to explain alone the variety of events so far recorded. The leading models consider magnetars as potential FRB sources. The recent detection of FRBs from the galactic magnetar SGR J1935+2154 seems to support them. Still, emission duration and energetic budget challenge all these models. Like for other classes of objects initially detected in a single band, it appeared clear that any solution to the FRB enigma could only come from a coordinated observational and theoretical effort in an as wide as possible energy band. In particular, the detection and localisation of optical/NIR or/and high-energy counterparts seemed an unavoidable starting point that could shed light on the FRB physics. Multiwavelength (MWL) search campaigns were conducted for several FRBs, in particular for repeaters. Here we summarize the observational and theoretical results and the perspectives in view of the several new sources accurately localised that will likely be identified by various radio facilities worldwide. We conclude that more dedicated MWL campaigns sensitive to the millisecond–minute timescale transients are needed to address the various aspects involved in the identification of FRB counterparts. Dedicated instrumentation could be one of the key points in this respect. In the optical/NIR band, fast photometry looks to be the only viable strategy. Additionally, small/medium size radiotelescopes co-pointing higher energies telescopes look a very interesting and cheap complementary observational strategy.

“…Besides FRB 180916B with 16.35-day periodic activity (CHIME/FRB Collaboration et al 2020b), some FRB sources and Galactic magnetars also appear possible periodic activities. The first repeating source, FRB 121102, showed a possible long period of ∼ 160 day (Rajwade et al 2020), and the X-ray bursts from Galactic magnetars SGR 1806-20 and SGR 1935+2154 were also found to have periodic activities of 398.2 day (Zhang et al 2021) and 237 day (Zou et al 2021), respectively. If these periodic activities are indeed due to the orbital periods of binary systems, FRB sources with bright radio bursts similar to the typical extragalactic FRBs might have opportunity to produce the observable optical transients if they are in Milky Way.…”

Optical Transients from Fast Radio Bursts Heating Companion Stars in Close Binary Systems

Fast radio bursts (FRBs) are bright radio transients with short durations and extremely high brightness temperatures, and their physical origins are still unknown. Recently, a repeating source, FRB 20200120E, was found in a globular cluster in the very nearby M81 galaxy. The associated globular cluster has an age of ∼ 9.13 Gyr, and hosts an old population of stars. In this work, we consider that an FRB source is in a close binary system with a low-mass main sequence star as its companion. Due to the large burst energy of the FRB, when the companion star stops the FRB, its surface would be heated by the radiation-induced shock, and make re-emission. For a binary system with a solar-like companion star and an orbital period of a few days, we find that the re-emission is mainly at optical band, and with delays of a few seconds after the FRB. Its luminosity is several times larger than the solar luminosity, and the duration is about hundreds of seconds. Such a transient might be observable in the future multiwavelength follow-up observation for Galactic FRB sources.

“…This object is so much closer than any other known FRB source that one could hope it could be some kind of "Rosetta stone" for understanding FRBs. (Another claim of PWB in soft gamma bursts was given for SGR1806-20 [11], though it is less certain. )…”

Astrophysical burst events such as fast radio bursts and some gamma ray events can repeat -periodically, without a clear pattern, clustered in time, or with activity occurring in periodic windows. We focus here on periodic windowed behavior, demonstrating methods for identifying it and characterizing it. Predictability of activity offers the opportunity to observe counterpart emission in other wavelengths and learn about the burst astrophysics. An important aspect is accounting for the "curious incident of the dog in the night time" -lack of bursts carries information. We analyze six years of data from the soft gamma repeater SGR1935+2154 as a worked example, deriving a period of 231 days and 55% duty cycle.
