Choosing the phase for the spin-weighted spheroidal functions
Gregory B. Cook, Xiyue Wang
The spin-weighted spheroidal functions are the eigenfunctions of the angular Teukolsky equation. They are a generalization of the widely used spin-weighted spherical functions, and…
Understanding solutions of the angular Teukolsky equation in the prolate asymptotic limit
Daniel J. Vickers, Gregory B. Cook
Solutions to the Angular Teukolsky Equation have been used to solve various applied problems in physics and are extremely important to black-hole physics, particularly in computing…
Aspects of multimode Kerr ring-down fitting
Gregory B. Cook
A black hole that is ringing down to quiescence emits gravitational radiation of a very specific nature that can inform us of its mass and angular momentum, test the no-hair theore…
An unknown branch of the total-transmission modes for the Kerr-geometry
Gregory B. Cook, Luke S. Annichiarico, Daniel J. Vickers
The gravitational modes of the Kerr geometry include both quasinormal modes and total-transmission modes. Sequences of these modes are parameterized by the angular momentum of the…
Modes of the Kerr geometry with purely imaginary frequencies
Gregory B. Cook, Maxim Zalutskiy
In this paper, we examine the behavior of modes of the Kerr geometry when the mode's frequency is purely imaginary. We demonstrate that quasinormal modes must be polynomial in natu…
Purely imaginary quasinormal modes of the Kerr geometry
Gregory B. Cook, Maxim Zalutskiy
We present a method for determining the purely imaginary quasinormal modes of the Kerr geometry. Such modes have previously been explored, but we show that prior results are incorr…
