Abstract

Fast radio bursts (FRBs) are brilliant short-duration flashes of radio emission originating at cosmological distances. Vast diversity in the properties of currently known FRBs and the fleeting nature of these events make it difficult to understand their progenitors and emission mechanisms. Some of the 'pulsar-like' properties of FRBs indicate their neutron star origin. Interestingly, the high-time-resolution properties of FRB 20210912A, a highly energetic event detected by the Australian Square Kilometre Array Pathfinder (ASKAP) in the Commensal Real-time ASKAP Fast Transients (CRAFT) survey, revealed remarkable resemblance with a previously reported CRAFT FRB, FRB 20181112A, including similar rest-frame emission timescales and polarization profiles. The observed properties of these two FRBs may be explained by emission from rapidly spinning neutron stars, with rest-frame spin periods of ∼ 1.1 ms — comparable to the shortest known period of a pulsar and close to the shortest possible rotation period of a neutron star. In this talk I will discuss the similarities between these two FRBs and their implications on FRB progenitor models.
