Black hole perturbations in modified gravity theories
Hugo Roussille
The recent first detection of gravitational waves (GWs) from binary black hole mergers has spurred a renewed interest in possible deviations from General Relativity (GR), since the…
On the effective metric of axial black hole perturbations in DHOST gravity
David Langlois, Karim Noui, Hugo Roussille
We study axial (or odd-parity) perturbations about static and spherically symmetric hairy black hole (BH) solutions in shift-symmetric DHOST (Degenerate Higher-Order Scalar-Tensor)…
Linear perturbations of Einstein-Gauss-Bonnet black holes
David Langlois, Karim Noui, Hugo Roussille
We study linear perturbations about non rotating black hole solutions in scalar-tensor theories, more specifically Horndeski theories. We consider two particular theories that admi…
A new look on black hole perturbations in modified gravity
Hugo Roussille
We study the linear perturbations about a nonrotating black hole solution of Horndeski's theory, using a systematic approach that extracts the asymptotic behaviour of perturbations…
