Black hole perturbations in modified gravity
David Langlois, Karim Noui, Hugo Roussille
We study the linear perturbations about nonrotating black holes in the context of degenerate higher-order scalar-tensor (DHOST) theories, using a systematic approach that extracts…

Asymptotics of linear differential systems and application to quasi-normal modes of nonrotating black holes
David Langlois, Karim Noui, Hugo Roussille
The traditional approach to perturbations of nonrotating black holes in General Relativity uses the reformulation of the equations of motion into a radial second-order Schrödinger-…
