Gravitational Waves from Green's Function Decomposition for a Kerr black hole: I. Equatorial ISCO Plunge
Junquan Su, Neev Khera, Abhishek Chowdhuri +2
We present a decomposition of the Kerr Green's function in the time domain, motivated by the frequency-domain split previously studied in the Schwarzschild limit. We show that the…

Green functions of the Regge-Wheeler and Teukolsky equations in Schwarzschild spacetime
David Q. Aruquipa, Marc Casals
We present a calculation of the full retarded Green functions of the Regge-Wheeler and Teukolsky equations obeyed by gravitational field perturbations of Schwarzschild spacetime. W…

Decomposition of Schwarzschild Green's Function
Junquan Su, Neev Khera, Marc Casals +3
We present a formulation of the spherically decomposed Green's function for a Schwarzschild black hole, based on a decomposition into two components, and , based on thei…
