![]() Burst timescales and luminosities link young pulsars and fast radio bursts. Prospects for high-precision pulsar timing with the new Effelsberg PSRIX backend. The discovery of cepheids and a new distance to M81. The Hubble Space Telescope Extragalactic Distance Scale Key Project. Fast radio bursts from magnetars born in binary neutron star mergers and accretion induced collapse. A nearby repeating fast radio burst in the direction of M81. A bright millisecond-duration radio burst from a Galactic magnetar. A concordance picture of FRB 121102 as a flaring magnetar embedded in a magnetized ion–electron wind nebula. The first CHIME/FRB fast radio burst catalog. Compact binaries are efficiently formed inside globular clusters, so a model invoking them could also be responsible for the observed bursts. We propose instead that FRB 20200120E originates from a highly magnetized neutron star formed either through the accretion-induced collapse of a white dwarf, or the merger of compact stars in a binary system 7. Globular clusters host old stellar populations, challenging FRB models that invoke young magnetars formed in a core-collapse supernova. Here we report observations that localized the FRB to a globular cluster associated with M81, where it is 2 parsecs away from the optical centre of the cluster. Recently, the discovery 6 of another repeater (FRB 20200120E) was announced, in the direction of the nearby galaxy M81, with four potential counterparts at other wavelengths 6. Many models invoke magnetically powered neutron stars (magnetars) as the source of the emission 4, 5. The majority of FRBs have been seen only once, although some are known to generate multiple flashes 2, 3.
