A repeating fast radio burst associated with a persistent radio | ResearchBunny

Abstract

This paper reports the detection and localization of the repeating fast radio burst (FRB) 20190520B, which is co-located with a compact, persistent radio source and associated with a dwarf host galaxy. The high host-galaxy dispersion measure suggests caution in inferring FRB redshifts without accurate host-galaxy identifications. The FRB exhibits a high burst rate and complex frequency-time intensity structure. Its properties are compared to other repeating FRBs, particularly FRB 20121102A.
