Model Description
This model considers FRBs from magnetars born in NS-NS mergers and accretion induced WD collapse. The FRBs themselves are formed by the same mechanism as that of giant flare FRB theories.
Observational Constraints
FRBs from magnetars born in NS-NS mergers and accretion induced WD collapse will be accompanied by persistent synchrotron radio emissionon timescales of months to years, powered by the nebula of relativistic electrons and magnetic fields inflated by the magnetar flares, or on longer timescales through interaction of the merger ejecta with the interstellar medium; this timescale is shorter than for the SLSN/LGRB channel.
The DM, RM and persistent radio emission in the model is consistent with
