Title: The Strongest Magnets in the Milky Way and Beyond

Abstract: Magnetars are isolated neutron stars that possess the strongest magnetic fields in the Universe. The most striking characteristic of magnetars is their emission of energetic bursts -- brief events lasting only a fraction of a second yet typically releasing energies exceeding 10^40 erg. On rare occasions, magnetars produce giant flares, which exhibit distinctive morphologies and release energy reaching or even surpassing 10^44 erg. This talk will provide an overview of magnetar bursts detected mostly with the Gamma-ray Burst Monitor on board Fermi Gamma-ray Space Telescope, with a particular focus on a prolific magnetar: SGR J1935+2154. This magnetar has emitted short radio bursts, including the first ever Galactic fast radio burst (FRB). There will also be a review of recent observations of magnetar giant flares from nearby galaxies.
