Model Description

When a BH evaporates to some critical mass, a fireball of e+/e− pairs can be created. The relativistic pairs expand into the magnetic field of the surrounding ISM, which, for a sufficiently low mass BH, could produce a emission consistent with an FRB.

Observational Constraints

In this scenario the inferred distance to the Lorimer burst is calculated to be <= 20 kpc, putting the source within out Galaxy. This theory is considered inviable.
