Implications of fast radio bursts for superconducting cosmic strings

Understand

Highly beamed, short-duration electromagnetic bursts could be produced by superconducting cosmic string (SCS) loops oscillating in cosmic magnetic fields.

• We demonstrated that the basic characteristics of SCS bursts such as the electromagnetic frequency and the energy release could be consistently exhibited in the recently discovered fast radio bursts (FRBs).
• Moreover, it is first showed that the redshift distribution of the FRBs can also be well accounted for by the SCS burst model.
• Such agreements between the FRBs and SCS bursts suggest that the FRBs could originate from SCS bursts and thus they could provide an effective probe to study SCSs.
