Linearized gravity on type D backgrounds — Steffen Aksteiner1,2 and •Lars Andersson3 — 1Quest Uni Hannover, Deutschland — 2Zarm Uni Bremen, Deutschland — 3MPI, Golm, Deutschland
In this talk I present joint work with Lars Andersson about the field equations of linearized gravity on a Petrov type D background, which includes Kerr spacetime. The Geroch Held Penrose (GHP) formalism is used to derive decoupled equations for all linearized Weyl scalars. The identification of gauge source functions leads to a generalized Regge-Wheeler equation. On Schwarzschild, a derivation of the gauge invariant Regge-Wheeler and Zerilli equation directly from the equation for the spin 0 scalar will be presented.
