Nonlinear Dynamics near the Threshold of Gravitational Collapse
Jaime Redondo-Yuste, Josu C. Aurrekoetxea
The authors use numerical relativity simulations of a self‑gravitating scalar field to compare perturbative expansions around flat spacetime with full nonlinear dynamics, identifyi…
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…
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…
Axial Oscillations of Viscous Neutron Stars
SofÃa 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…
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…
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…
