According to the Blandford-Znajek mechanism, black hole jets are powered by the rotational energy of the compact object. In this work, we consider the possibility that the metric around black holes may not be described by the Kerr solution and we study how this changes the Blandford-Znajek model. If the Blandford-Znajek mechanism is responsible for the formation of jets, the estimate of the jet power in combination with another measurement can test the nature of black hole candidates and constrain possible deviations from the Kerr solution. However, this approach might become competitive with respect to other techniques only when it will be possible to have measurements much more precise than those available today.

  1. Universality of the Blandford-Znajek emission in stationary and axisymmetric spacetimes

    gr-qc 2026-02 conditional novelty 7.0 of 10

    The Blandford-Znajek jet luminosity is universal (∝Ω_h²) at leading order across parametric black-hole spacetimes and spacetime-dependent at next order, breaking the low-spin degeneracy for rapidly rotating holes.

  2. Regular Rotating Black Hole: Probing the boundaries of the Radiative Signatures and Jet Power

    astro-ph.HE 2025-08 conditional novelty 5.0 of 10

    MOG regular rotating black holes are compatible with most X-ray binary data only for beta below about 0.38 to 0.4, and are excluded for the near-extremal source GRS 1915+105.
