Fast Radio Bursts (FRBs) are millisecond-duration events detected from beyond our Milky Way Galaxy. FRB emission characteristics favor magnetars as their sources, as evidenced by FRB-like bursts from a magnetar in the Milky Way, and the star-forming nature of FRB host galaxies. However, the processes that produce FRB sources remain unknown.
