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…
