General relativistic massive vector field effects in Gamma Ray Burst production

arXiv:1603.01464 · doi:10.1103/PhysRevD.96.104003

Abstract

To explain the extremely high energy release, ~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, , with a clear dependence on the BH mass, , and charge, , and can extract energies up to 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.
