Rotating Bardeen-Ghosh black holes

Abstract We found rotating regular Bardeen-Ghosh black holes (BHs), obtained from an exact spherically symmetric seed BH metric sourced by nonlinear electrodynamics (NED) with a quantum-gravitymotivated short-distance suppression. The rotating regular Bardeen-Ghosh black holes (BHs) are asymptotically flat and go over to the Kerr BH geometry in the limit. We analyse the horizon structure and demonstrate that the regularization parameters modify the extremality condition, thereby reducing the maximum allowed spin. We have also studied the radially dependent quasilocal Komar quantities M ef f and J ef f , which are finite and, at large radial distances, approximate the ADM mass (M ) and angular momentum (M a), respectively. A generalised Smarr relation and a modified first law are employed to provide a consistent thermodynamic description. Our results indicate that the rotating regular Bardeen-Ghosh (BHs), provide a physically viable alternative to the Kerr solution and offer a valuable setting for investigating possible strong-field deviations from classical general relativity.
