Quasinormal-mode stability bounds in gravitational EFT: resolvability, predictivity, and positivity
Leonardo Juliano, Enrico Trincherini
It has been proposed that consistency limits how slowly black holes can ring down in extensions of General Relativity: effective-field-theory (EFT) corrections may lengthen the dec…
On the Asymptotic Causal Structure in Gravitational EFTs
Bruno Bucciotti, Paolo Creminelli, Alessandro Longo +2
It is usually assumed that a healthy EFT should not allow superluminal propagation. In the presence of gravity, however, the notion of superluminality becomes subtle, since there i…
Screening of dipolar emission in two-scale Gauss-Bonnet gravity
Farid Thaalba, Leonardo Gualtieri, Thomas P. Sotiriou +1
We study black holes in shift-symmetric scalar Gauss-Bonnet gravity extended by a cubic Galileon interaction with a distinct energy scale. Introducing this hierarchy profoundly mod…
Amplitudes and Polarizations of Quadratic Quasi-Normal Modes for a Schwarzschild Black Hole
Bruno Bucciotti, Leonardo Juliano, Adrien Kuntz +1
General Relativity predicts the existence of quadratic quasi-normal modes at second order in perturbation theory. Building on our recent work, we compute the amplitudes and polariz…
Quadratic Quasi-Normal Modes of a Schwarzschild Black Hole
Bruno Bucciotti, Leonardo Juliano, Adrien Kuntz +1
Quadratic quasi-normal modes, generated at second order in black hole perturbation theory, are a promising target for testing gravity in the nonlinear regime with next-generation g…
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…
Interplay between Black Holes and Ultralight Dark Matter: Analytic Solutions
Bruno Bucciotti, Enrico Trincherini
Dark matter (DM) can consist of a scalar field so light that DM particles in the galactic halo are best described by classical waves. We investigate how these classical solutions a…
