Tests of scalar polarizations with multi-messenger events
Sk Md Adil Imam, Macarena Lagos
Gravitational wave (GW) observations provide a unique opportunity to test Einstein's General Relativity (GR) in the strong-field regime. While GR predicts only two tensor polarizat…
Nonlinearities in Gravity: Gravitational Wave Ringdown
Macarena Lagos
The modeling of gravitational wave ringdown has traditionally relied on linear perturbation theory, which mainly describes the late-time behavior of a perturbed black hole after a…
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…
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…
The impact of initial conditions on quasi-normal modes
Ameya Chavda, Macarena Lagos, Lam Hui
This study investigates the influence of initial conditions on the evolution and properties of linear quasi-normal modes (QNMs). Using a toy model in which the quasi-normal mode ca…
