Description

"2020 was a special year for magnetar studies. The first simultaneous detection
of an FRB-like radio burst from a Galactic magnetar and its high-energy counterpart
(FRB/SGR 200428) suggests that magnetars can produce FRBs.
Observations of the short γ-ray burst GRB 200415A, associated with a nearby galaxy
and with properties closely resembling the huge initial pulses of magnetar
giant flares (MGF), made this event, and its "twin" GRB 051103, the most promising
candidates for extragalactic MGFs. We report on hard X-ray/gamma-ray properties
of these events obtained with the Konus-Wind GRB experiment and discuss their
implications for magnetar/FRB and magnetar/GRB connections
