New wrinkles on black hole perturbations: Numerical treatment of acoustic and gravitational waves
by Tenyotkin, Valery, Ph.D., The University of North Carolina at Chapel Hill, 2009, 159; 3354519
Abstract (Summary)

This thesis develops two main topics. A full relativistic calculation of quasinormal modes of an acoustic black hole is carried out. The acoustic black hole is formed by a perfect, inviscid, relativistic, ideal gas that is spherically accreting onto a Schwarzschild black hole.

The second major part is the calculation of sourceless vector (electromagnetic) and tensor (gravitational) covariant field evolution equations for perturbations on a Schwarzschild background using the relatively recent [special characters omitted] decomposition method. Scattering calculations are carried out in Schwarzschild coordinates for electromagnetic and gravitational cases as validation of the method and the derived equations.
