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…

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…
