Black hole jet power from impedance matching

Black hole jet power depends on the angular velocity of magnetic field lines, Ω[subscript F]. Force-free black hole magnetospheres typically have Ω[subscript F]/Ω[subscript H] ≈ 0.5, where Ω[subscript H] is the angular velocity of the horizon. We give a streamlined proof of this result using an exte...
