    Abstract

    A Kerr-de Sitter black hole loses energy and angular momentum through both quantum superradiance and thermal emission. Our investigation of the former process indicates that a rapidly rotating black hole spins down faster as we increase Λ, but after spinning down takes longer to evaporate.
