Quasinormal Modes and the Switchback Effect in Schwarzschild-de Sitter
Mir Mehedi Faruk, Facundo Rost, Jan Pieter van der Schaar
We study the causal structure of Schwarzschild-de Sitter (SdS), including shock wave perturbations, in using reflected null ray trajectories, either through the interior blac…
