Energy extraction from a Kerr-Bardeen-Letelier black hole by Comisso-Asenjo Mechanism

Year: 2026

Type: preprint

Abstract: We explore the energy extraction from a Kerr-like regular black hole coupled with a cloud of strings (CoS) via the Comisso-Asenjo mechanism. We study the effects of the black hole spin (a), black hole charge (g) and CoS parameter (b) on the ergo-region of the black hole and the magnetic reconnection process, which is governed by the Comisso-Asenjo mechanism. We also analyze the phase space involving negative energy density of the relativistic magnetized plasma at infinity. The rate of energy extraction in the magnetic reconnection process is also computed and compared with that of the Blandford-Znajek mechanism.
