Model Description

For merging BH binaries in which at least one of the BHs is Kerr-Newman, instabilities due to tidal forces induce reconnection in the KNBH prior to coalescence. The magnetic field violently reconnects, triggering strong relativistic shock waves through the surrounding plasma to produce curvature radiation consistent with an FRB.

Observational Constraints

KNBHs have no thermal emission because they lack solid surfaces, and are non-pulsating because their magnetic and rotation axes are aligned.
