Quasi-stationary binary inspiral II: Radiation-balanced boundary conditions
John T. Whelan, William Krivan, Richard Price
The quasi-stationary method for black hole binary inspiral is an approximation for studying strong field effects while suppressing radiation reaction. In this paper we use a nonlin…
Late-Time Dynamics of Scalar Fields on Rotating Black Hole Backgrounds
William Krivan
Motivated by results of recent analytic studies, we present a numerical investigation of the late-time dynamics of scalar test fields on Kerr backgrounds. We pay particular attenti…
Initial data for superposed rotating black holes
W. Krivan, R. H. Price
The standard approach to initial data for both analytic and numerical computations of black hole collisions has been to use conformally-flat initial geometry. Among other advantage…
Kerr-like initial data for the collision of two locally Kerr holes
William Krivan, Richard H. Price
A technical flaw was found in this paper, and it has been withdrawn. It is intended that a modified version will be submitted soon.
The imposition of Cauchy data to the Teukolsky equation III: The rotating case
Manuela Campanelli, Carlos O. Lousto, John Baker +2
We solve the problem of expressing the Weyl scalars that describe gravitational perturbations of a Kerr black hole in terms of Cauchy data. To do so we use geometrical identiti…
Dynamics of scalar fields in the background of rotating black holes II: A note on superradiance
Nils Andersson, Pablo Laguna, Philippos Papadopoulos
We analyze the amplification due to so-called superradiance from the scattering of pulses off rotating black holes as a numerical time evolution problem. We consider the "worst pos…
