Description
Historically the Teukolsky equation corresponding to gravitational perturbations is solved for the Weyl scalars. However, reconstructing the metric from these scalars involves solving a fourth order PDE to obtain the Hertz potential and then another second order PDE to construct the metric perturbation. Solving the (adjoint) Teukolsky equation for the Hertz potential directly simplifies the metric reconstructions procedure to just one second order PDE. We discuss using this method in the time domain with a point particle source and its foreseeable application in self-force calculations.
