Strong-lensing rates of massive black hole binaries in LISA
Juan Gutiérrez, Macarena Lagos
Similarly to electromagnetic (EM) signals, gravitational lensing by intervening galaxies can also affect gravitational waves (GWs). In this paper, we estimate the strong-lensing ra…

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…
