Fast radio burst -- persistent radio source systems. I. A 1.2 GHz search and catalog definition
Fast radio bursts (FRBs) are millisecond-duration radio transients observed at extragalactic distances, whose origin remains uncertain. Given their extremely short duration and high implied luminosities, magnetars are commonly identified as sources of FRBs. A small (∼ 2%) fraction of FRBs are known to repeat, but it is...
