Dynamics of perturbations of rotating black holes
Dynamics of perturbations of rotating black holes
We present a numerical study of the time evolution of perturbations of rotating black holes. The solutions are obtained by integrating the Teukolsky equation written as a first order in time, coupled system of equations. We address the numerical difficulties of solving the equation in its original form. We follow the propagation of generic initial data through the burst, quasinormal ringing and power-law tail phases. In particular, we calculate the effects due to the rotation of the black hole on the scattering of incident gravitational wave pulses. These effects include the amplitude enhancement due to so-called super-radiance. The results may help explain how the angular momentum of the black hole affects the gravitational waves that are generated during the final stages of black hole coalescence.

Abstract
We present a numerical study of the time evolution of perturbations of rotating black holes. The solutions are obtained by integrating the Teukolsky equation written as a first order in time, coupled system of equations. We address the numerical difficulties of solving the equation in its original form. We follow the propagation of generic initial data through the burst, quasinormal ringing and power-law tail phases. In particular, we calculate the effects due to the rotation of the black hole on the scattering of incident gravitational wave pulses. These effects include the amplitude enhancement due to so-called super-radiance. The results may help explain how the angular momentum of the black hole affects the gravitational waves that are generated during the final stages of black hole coalescence.
