Accurate Black Hole Quasinormal Modes, Regge Poles, and Greybody Factors from Light Ring Ladder Symmetry
Rajes Ghosh, David Pereñiguez, Jaime Redondo-Yuste +1
The characteristic oscillations of a black hole can be understood in terms of null rays trapped near its unstable light ring, with this correspondence becoming exact in the high-fr…
Second-order scattering response of a Schwarzschild black hole
Bruno Bucciotti, Jaime Redondo-Yuste, Adrien Kuntz +2
Gravitational waves couple in a nonlinear fashion in the vicinity of a black hole. Black hole perturbation theory can be readily applied to compute the magnitude of this coupling,…
Nonlinear Dynamics near the Threshold of Gravitational Collapse
Jaime Redondo-Yuste, Josu C. Aurrekoetxea
Perturbation theory is an essential tool to model and interpret gravitational dynamics, for example, binary black hole mergers. Therefore it is also crucial to precisely understand…
Black Hole Ringdown Nonlinearities in the Large-D Limit
Roberto Emparan, Amanda Green-Salinas, David Pereñiguez +1
We initiate the study of nonlinear effects in the ringdown phase of black hole mergers using the effective theory of black hole dynamics in the large-D limit. This framework offers…
Ringdown and lensing of triple systems
Vitor Cardoso, Giuseppe Ficarra, Jaime Redondo-Yuste +1
Triple systems have progressively been recognized as ubiquitous in our Universe and provide a good testing ground for wave generation and propagation in nontrivial environments. We…
Axial Oscillations of Viscous Neutron Stars
Sofía Bussières, Jaime Redondo-Yuste, José Javier Ortega Gómez +1
The oscillation modes of stars play an important role in observations, and on the understanding of stellar stability properties. The role of viscosity in the oscillation modes of c…
Nonlinear Dynamics in General Relativity
Vitor Cardoso, Jaime Redondo-Yuste, Ulrich Sperhake +1
Black holes and gravitational waves are consequences of the nonlinear character of the Einstein equations. Yet, the remarkable properties of General Relativity point to the existen…
Radial Oscillations of Viscous Stars
Lennox S. Keeble, Jaime Redondo-Yuste
Oscillation modes of neutron stars, a key target for third-generation gravitational wave detectors, encode key information about their constituent nuclear matter. In this work, we…
