Second order gauge invariant gravitational perturbations of a Kerr black hole
M. Campanelli, C. O. Lousto
We investigate higher than the first order gravitational perturbations in the Newman-Penrose formalism. Equations for the Weyl scalar representing outgoing gravitational rad…
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…
The imposition of Cauchy data to the Teukolsky equation II: Numerical comparison with the Zerilli-Moncrief approach to black hole perturbations
Manuela Campanelli, William Krivan, Carlos O. Lousto
We revisit the question of the imposition of initial data representing astrophysical gravitational perturbations of black holes. We study their dynamics for the case of nonrotating…
