In this talk we will review the main observational and theoretical evidences that point toward a magnetars as FRB progenitors.

The galactic magnetar SGR 1935+2154 provided on April 28, 2020 the first observational evidence for a connection between magnetars and FRBs. Since then this magnetar has attracted much interest and several observational campaigns and detailed studies of its behavior have been performed.

This has also been facilitated by the fact that SGR 1935+2154 has been the most active magnetars in the... -

During this presentation I will present recent advancements on the study of fast radio bursts (FRBs) – short, energetic radio flashes of extragalactic origin, with typical durations of a millisecond – through low frequency observations conducted with the Northern Cross radio telescope. In particular, I will show how long-term radio monitoring of a sample of nearby galaxies can help investigate...

he radio emission from magnetars is poorly understood and characterized observationally, in particular for what concerns single pulses and sporadic events.

The interest in it was boosted by the recent detection of an extremely bright ms radio signal from the Galactic magnetar SGR 1935+2154, which occurred almost simultaneously with a typical magnetar short burst of X-rays.
As of now, this... -

The first observational evidence linking magnetars and Fast Radio Bursts (FRBs) was the detection of simultaneous radio and X-ray bursts from the Galactic magnetar SGR 1935+2154 in 2020.

We analysed over 25 hours of observations from the Large-Sized Telescope prototype (LST-1) of the Cherenkov Telescope Array Observatory (CTAO) during periods of high-energy activity in 2021 and 2022,...
