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…
A Quantum of Hope
Shawn E. S. Skelton, Anna Knörr, Jaime Redondo-Yuste +2
Public outreach in quantum science and technologies has many goals, ranging from generating interest and dampening hype to making the fascinating and complex topic more accessible.…
Perturbations of Plane Waves and Quadratic Quasinormal Modes on the Lightring
Kwinten Fransen, David Pereñiguez, Jaime Redondo-Yuste
We study second order gravitational perturbations on plane wave spacetimes from both the metric and curvature perturbation points of view. For the former, we explicitly use the iso…
Superradiant amplification by rotating viscous compact objects
Jaime Redondo-Yuste, Vitor Cardoso
We study fluctuations of rotating viscous stars, using the causal relativistic hydrodynamics of Bemfica, Disconzi, Kovtun, and Noronha. We derive, in a slow-rotation approximation,…
Black hole spectroscopy: from theory to experiment
Emanuele Berti, Vitor Cardoso, Gregorio Carullo +65
The "ringdown" radiation emitted by oscillating black holes has great scientific potential. By carefully predicting the frequencies and amplitudes of black hole quasinormal modes a…
Perturbative and non-linear analyses of gravitational turbulence in spacetimes with stable light rings
Jaime Redondo-Yuste, Alejandro Cárdenas-Avendaño
Some black hole mimickers, as well as black strings and other higher-dimensional spacetimes, exhibit stable light rings-regions where light or high-frequency gravitational waves ca…
Lensing and wave optics in the strong field of a black hole
Juno C. L. Chan, Conor Dyson, Matilde Garcia +2
Gravitational waves (GWs) are lensed by matter, offering a unique probe of both the large-scale structure of the Universe and the fundamental properties of GW propagation. GWs can…
Ringdown nonlinearities in the eikonal regime
Bruno Bucciotti, Vitor Cardoso, Adrien Kuntz +2
The eikonal limit of black hole quasinormal modes (the large multipole limit ) can be realized geometrically as a next-to-leading order solution to the geometric optics…
The dynamical response of viscous objects to gravitational waves
Valentin Boyanov, Vitor Cardoso, Kostas D. Kokkotas +1
We study the dynamical response of viscous materials to gravitational waves, in the context of a fully relativistic theory of fluid dynamics. For the first time, we calculate oscil…
Perturbations of relativistic dissipative stars
Jaime Redondo-Yuste
Viscous fluids can dissipate and alter the propagation of gravitational waves, as well as modify the relaxation and stability properties of self-gravitating fluids. This is particu…
Hushing black holes: tails in dynamical spacetimes
Vitor Cardoso, Gregorio Carullo, Marina De Amicis +6
Stationary, asymptotically flat, black hole solutions of the vacuum field equations of General Relativity belong to the Kerr family. But how does one approach this state, dynamical…
Relativistic aerodynamics of spinning black holes
Conor Dyson, Jaime Redondo-Yuste, Maarten van de Meent +1
Astrophysical black holes do not exist in vacuum, and their motion is affected by the galactic environment. As a black hole moves it attracts stars and matter, creating a wake that…
Ringdown of a dynamical spacetime
Jaime Redondo-Yuste, David Pereñiguez, Vitor Cardoso
The gravitational waves emitted (some time) after two black holes merge are well described by the theory of linear perturbations on a spacetime characterized by the mass and spin o…
Twisted traces on abelian quantum Higgs and Coulomb branches
Davide Gaiotto, Justin Hilburn, Jaime Redondo-Yuste +2
We study twisted traces on the quantum Higgs branches of gauge theories, that is, the quantum Hamiltonian reductions of Weyl algebras…
Spin dependence of black hole ringdown nonlinearities
Jaime Redondo-Yuste, Gregorio Carullo, Justin L. Ripley +2
The nonlinear character of general relativity leaves its imprint in the coalescence of two black holes, from the inspiral to the final ringdown stage. To quantify the impact of non…
Eternal binaries
Jaime Redondo-Yuste, Vitor Cardoso, Caio F. B. Macedo +1
The two-body problem is extensively studied in open systems and asymptotically flat spacetimes. However, there are many systems where radiation is trapped: they range from radiatin…
Non-linear black hole dynamics and Carrollian fluids
Jaime Redondo-Yuste, Luis Lehner
The dynamics of black hole horizons has recently been linked to that of Carrollian fluids. This results in a dictionary between geometrical quantities and those of a fluid with unu…
