“…One natural question is whether magnetars can account for all the FRBs observed in the universe. The bursting rate of SGRs in the universe is about 10 2 − 10 3 times more often than the FRB rate 52,79 . Considering the approximately 10 −2 − 10 −3 rarity factor of SGR-FRB associations, one is tempted to draw the conclusion that all (or at least the majority of)…”

Fast radio bursts are mysterious millisecond-duration transients prevalent in the radio sky. Rapid accumulation of data in recent years has facilitated an understanding of the underlying physical mechanisms of these events. Knowledge gained from the neighboring fields of gamma-ray bursts and radio pulsars also offered insight. Here I review developments in this fast-moving field.Two generic categories of radiation model invoking either magnetospheres of compact objects (neutron stars or black holes) or relativistic shocks launched from such objects have been much debated. The recent detection of a Galactic fast radio burst in association with a soft gamma-ray repeater suggests that magnetar engines can produce at least some, and probably all, fast radio bursts. Other engines that could produce fast radio bursts are not required, but are also not impossible. On 24 July, 2001, a bright, dispersed radio pulse reached the Parkes 64-m telescope in Australia. The recorded signal remained unnoticed until Duncan Lorimer and his collaborators discovered it (now known as the fast radio burst FRB 010724) several years later and published the results in Science 1. For some time, some astronomers were not convinced that this so-called "Lorimer burst" was a genuine type of astrophysical event, until four more events were reported in 2013 (ref. 2). The field then enjoyed a rapid boost from both observational and theoretical fronts. With the identification of the microwave-oven-origin of some artificial bursts known as "perytons", the astrophysical origin of the bona fide bursts was finally established 3. This was followed by the detection of the first repeating source, known as FRB 121102 (ref. 4) and its localization in a dwarf star forming galaxy at redshift z = 0.19(refs. 5-7), establishing the extragalactic/cosmological origin (in contrast to the Galactic origin 8) of these events. Numerous theoretical models have been proposed to interpret these mysterious events 9. These have been driven by observations and groundbreaking results from numerous radio observatories: Parkes, Arecibo, Green Bank Telescope, the 1

Fast radio bursts (FRB) are enigmatic powerful single radio pulses with durations of several milliseconds and high brightness temperatures suggesting coherent emission mechanism. For the time being a number of extragalactic FRBs have been detected in the high-frequency radio band including repeating ones. The most plausible explanation for these phenomena is magnetar hyperflares. The first observational evidence of this scenario was obtained in April 2020 when an FRB was detected from the direction of the Galactic magnetar and soft gamma repeater SGR1935+2154. The FRB was preceded with a number of soft gamma-ray bursts observed by Swift-BAT satellite, which triggered the follow-up program of the H.E.S.S. imaging atmospheric Cherenkov telescopes (IACTs). H.E.S.S. has observed SGR1935+2154 over a 2 hour window few hours prior to the FRB detection by STARE2 and CHIME. The observations overlapped with other X-ray bursts from the magnetar detected by INTEGRAL and Swift-BAT, thus providing first observations of a magnetar in a flaring state in the very-high energy domain. We present the analysis of these observations, discuss the obtained results and prospects of the H.E.S.S. follow-up program for soft gamma repeaters and anomalous X-ray pulsars.
