Nonlinear Quasi-Normal Modes: Uniform Approximation
Bruno Bucciotti, Adrien Kuntz, Francesco Serra +1
Recent works have suggested that nonlinear (quadratic) effects in black hole perturbation theory may be important for describing a black hole ringdown. We show that the technique o…
Causality Constraints on Black Holes beyond GR
Francesco Serra, Javi Serra, Enrico Trincherini +1
We derive causality constraints on the simplest scalar-tensor theories in which black holes differ from what General Relativity predicts, a scalar coupled to the Gauss-Bonnet or th…
Effective two-body approach to the hierarchical three-body problem
Adrien Kuntz, Francesco Serra, Enrico Trincherini
The motion of three bodies can be solved perturbatively when a tightly bound inner binary is orbited by a distant perturber, giving rise for example to the well-known Kozai-Lidov o…
Hairy Black-holes in Shift-symmetric Theories
Paolo Creminelli, Nicolás Loayza, Francesco Serra +2
Scalar hair of black holes in theories with a shift symmetry are constrained by the no-hair theorem of Hui and Nicolis, assuming spherical symmetry, time-independence of the scalar…
