Neutrino Quasinormal Modes of a Kerr-Newman-de Sitter Black Hole
Jia-Feng Chang, You-Gen Shen
Abstract
Using the Pöshl-Teller approximation, we evaluate the neutrino quasinormal modes (QNMs) of a Kerr-Newman-de Sitter black hole. The result shows that for a Kerr-Newman-de Sitter black hole, massless neutrino perturbation of large Λ, positive m and small value of n will decay slowly.
