“…Early on, there were doubts as to whether FRBs were truly astrophysical until a new sample was identified in 2013 (Thornton et al 2013). Ever since then, this mysterious phenomenon has started to attract intense attention from the community, with breakthroughs announced consistently (for reviews, see Katz 2018;Popov et al 2018;Petroff et al 2019;Cordes & Chatterjee 2019;Zhang 2020;Xiao et al 2021;Petroff et al 2021). One striking achievement to note is the discovery of the first repeating event FRB 20121102A in 2016 (Spitler et al 2016;Scholz et al 2016) and later the identification of its host galaxy (Chatterjee et al 2017;Marcote et al 2017;Tendulkar et al 2017).…”

“…Up to now, there have been more than 20 repeaters and 600 apparently non-repeating FRBs listed in the catalog (Petroff et al 2016; The CHIME/FRB Collaboration 2021). However, it is still under hot debate whether genuinely non-repeating FRBs exist (Caleb et al 2018(Caleb et al , 2019Palaniswamy et al 2018;Xiao et al 2021). A few works have discussed the possibility to judge this question using the number fraction of repeaters (Caleb et al 2019;Lu et al 2020;Ai et al 2021;Gardenier et al 2021).…”

The total number of observed fast radio burst (FRB) events is rising rapidly thanks to the improvement of existing radio telescopes and the delivery of new facilities. In particular, the Five-hundred-meter Aperture Spherical radio Telescope Collaboration recently reported more than one thousand bursts in a short observing period of 47 days. The striking bimodal distribution in their work motivated us to revisit the definition of FRBs. In this work, we ascribe the bimodal distribution to two physical kinds of radio bursts that may exhibit different radiation mechanisms. We propose using brightness temperature to separate two subtypes. For FRB 20121102A, the critical brightness temperature is TB, cri ≃ 1033 K. Bursts with TB ≥ TB, cri are denoted as “classical” FRBs and we find a tight pulse width-fluence relation (T ∝ ℱν0.306) for them. On the contrary, the other bursts are considered as “atypical” bursts that may have originated from a different type of physical process. We suggest that for each FRB event, a similar dividing line should exist but that the TB, cri is not necessarily the same in such cases. Its exact value depends on the FRB radiation mechanism and the properties of the source.

“…Fast radio bursts (FRBs) are extragalactic radio flares with millisecond duration discovered by [121]. The question of their origin is one of the major astrophysical mysteries nowadays (see reviews, e.g., in [122][123][124]). Axion to photon conversion in a strong magnetic field was one of the first scenarios involving astroparticle physics.…”

Astroparticle Physics with Compact Objects

Probing the existence of hypothetical particles beyond the Standard model often deals with extreme parameters: large energies, tiny cross-sections, large time scales, etc. Sometimes, laboratory experiments can test required regions of parameter space, but more often natural limitations lead to poorly restrictive upper limits. In such cases, astrophysical studies can help to expand the range of values significantly. Among astronomical sources, used in interests of fundamental physics, compact objects—neutron stars and white dwarfs—play a leading role. We review several aspects of astroparticle physics studies related to observations and properties of these celestial bodies. Dark matter particles can be collected inside compact objects resulting in additional heating or collapse. We summarize regimes and rates of particle capturing as well as possible astrophysical consequences. Then, we focus on a particular type of hypothetical particles—axions. Their existence can be uncovered due to observations of emission originated due to the Primakoff process in magnetospheres of neutron stars or white dwarfs. Alternatively, they can contribute to the cooling of these compact objects. We present results in these areas, including upper limits based on recent observations.

“…Fast Radio Bursts (FRBs) are bright (50 mJy -100 Jy [1]), ∼ms duration radio bursts, occurring in extra-galactic environments [2], from an unknown class of progenitor [3]. For a recent review of the fundamentals of FRBs see Petroff, 2019 [1].…”

Fast radio burst (FRBs) are an exciting class of bright, extragalactic, millisecond radio transients. The recent development of large field-of-view (FOV) radio telescopes has caused a rapid rise in the number of identified single burst and repeating FRBs. This has allowed for the extensive multiwavelength follow-up to search for the potential counterparts predicted by theoretical models. New observations of similar radio transients in Galactic magnetars like SGR 1935+2154 have continued to motivate the search for rapid optical and very-high-energy (VHE, >100 GeV) counterparts. Since 2016 VERITAS has engaged in an FRB observing campaign to search for the prompt optical, and VHE emission from multiple repeating FRBs. We present these new results from VERITAS observations of five repeating sources including data taken simultaneously with bursts observed by the CHIME radio telescope.
