Model Description

In this model, FRBs are generated from forward shocks of blast waves decelerating into the previously decelerated waves. An example of these blast waves are flare ejecta from young magnetars. The ejected material also produces a persistent radio source and a source of high local dispersion measure and high rotation measure. The flares are expected to produce prompt gamma-ray, X-ray and possibly optical flares.

Observational Constraints

Observation of a persistent radio source, location in a dwarf galaxy, measurement of high rotation measure for the CHIME/FRB repeater would be a good way to test the model.
