General relativistic massive vector field effects in Gamma Ray Burst production

TL;DR

This paper proposes a new energy extraction mechanism from rotating black holes using a massive photon field, potentially explaining the high energies observed in Gamma Ray Bursts without requiring collimation.

Contribution

It introduces a novel theoretical model for energy extraction from Kerr-Newman black holes via a massive photon field, with numerical validation of its stability and energy output.

Findings

Can extract energies up to 10^{54} erg from black holes.

Mechanism is stable across different black hole rotation parameters.

Provides a lower bound on electromagnetic-gravitational coupling.

Abstract

To explain the extremely high energy release, $>10^{53}$~erg, suggested by the observations of some Gamma Ray Bursts (GRBs) we propose a new energy extraction mechanism from the rotation energy of a Kerr-Newman black hole (BH) by a massive photon field. Numerical results show that this mechanism is stable with respect to the black hole rotation parameter, $a$, with a clear dependence on the BH mass, $M$, and charge, $Q$, and can extract energies up to $10^{54}$ erg. The controversial "energy crisis" problem of GRBs that does not show evidence for collimated emission may benefit of this energy extraction mechanism. With these results we set a lower bound on the coupling between electromagnetic and gravitational fields.
