Publication on Kerr black hole momentum by Assistant Professor of Physics Robert Owen

Recently published:  Lovelace, G; Scheel, MA; Owen, Robert, Physics & Astronomy Dept; Giesler, M; et al. 2015.

Nearly extremal apparent horizons in simulations of merging black holes.
Classical and Quantum Gravity 32(6):065007  [A journal from Institute of Physics @ IoPScience]

Partial abstract:
The spin angular momentum S of an isolated Kerr black hole is bounded by the surface area A of its apparent horizon: 8 pi S A. We show that the overspun surfaces are indeed superextremal: our lower bound on their Booth-Fairhurst extremality exceeds unity. However, we confirm that these superextremal surfaces are always surrounded by marginally outer trapped surfaces (i.e., by apparent horizons) with 8 pi S < A. The extremality lower bound on the enclosing apparent horizon is always less than unity but can exceed the value for an extremal Kerr black hole.
