Model Description

When a BH evaporates to some critical mass, a fireball of electron-positron pairs can be created. The relativistic pairs expand into the magnetic field of the surrounding ISM, which could produce emission consistent with an FRB. The inferred distance for the Lorimer burst in this scenario, however, is calculated to be <20 kpc. This would place the source within our galaxy, and thus the theory is rendered void.
