Nonlinear generation of harmonics in highly distorted black holes
Abstract
Simulations of highly distorted black holes provide us with a suitable system to investigate the generation of nonlinear harmonics in black-hole oscillations. We conduct numerical experiments of the scattering of a large amplitude perturbation incident on a black hole in order to investigate the harmonic content of the scattered wave. Papapadopoulos (2002) found that nonlinear coupling is inefficient in channeling energy away from the dominate mode. We expand on this work by studying the scattered wave's dependence on the azimuthal quantum number, m, and the effects of larger amplitude waves. This experiment has direct implications to data analysis efforts by making it possible to estimate the family of modes relevant to the design of software detection tools.
