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…
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…
Quadratic DHOST theories revisited
David Langlois, Karim Noui, Hugo Roussille
We present a novel and remarkably simple formulation of degenerate higher-order scalar-tensor (DHOST) theories whose Lagrangian is quadratic in second derivatives of some scalar fi…
Excited hairy black holes: dynamical construction and level transitions
Pablo Bosch, Stephen R. Green, Luis Lehner +1
We study the dynamics of unstable Reissner-Nordström anti-de Sitter black holes under charged scalar field perturbations in spherical symmetry. We unravel their general behavior an…
