Figure 11: Evolution of a highly spinning BH (a∕M = 0.99) during interaction with different frequency GW packets, each with initial mass ≈ 0.1M. Shown (in units where M = 1) are the mass, irreducible mass, and angular momentum of the BH as inferred from AH properties. Image reproduced with permission from [289], copyright by APS.
