Black hole quasinormal modes using the asymptotic iteration method. (English) Zbl 1197.83065

Summary: We show that the asymptotic iteration method (AIM) allows one to numerically find the quasinormal modes of Schwarzschild and Schwarzschild de Sitter black holes. An added benefit of the method is that it can also be used to calculate the Schwarzschild anti-de Sitter quasinormal modes for the case of spin-zero perturbations. We also discuss an improved version of the AIM, more suitable for numerical implementation.
