Transient Instability of Rapidly Rotating Black Holes
Samuel E. Gralla, Aaron Zimmerman, Peter Zimmerman
We analytically study the linear response of a near-extremal Kerr black hole to external scalar, electromagnetic, and gravitational field perturbations. We show that the energy den…

Horizon Instability of Extremal Kerr Black Holes: Nonaxisymmetric Modes and Enhanced Growth Rate
Marc Casals, Samuel E. Gralla, Peter Zimmerman
We show that the horizon instability of the extremal Kerr black hole is associated with a singular branch point in the Green function at the superradiant bound frequency. We study…

Gravitational self-force in nonvacuum spacetimes
Peter Zimmerman, Eric Poisson
The gravitational self-force has thus far been formulated in background spacetimes for which the metric is a solution to the Einstein field equations in vacuum. While this formulat…
