Black hole spectroscopy with nonlinear quasi-normal modes
Macarena Lagos, Tomás Andrade, Jordi Rafecas-Ventosa +1
The future detection of quasi-normal modes (QNMs) from black hole ringdown will allow for consistency and independent tests of general relativity (GR) in the strong-field regime. I…

A numerical-relativity surrogate model for hyperbolic encounters of black holes: challenges in parameter estimation
Joan Fontbuté, Tomas Andrade, Raimon Luna +5
We present a surrogate numerical-relativity model for close hyperbolic black-hole encounters with equal masses and spins aligned with the orbital momentum. Our model, generated in…
