Chiral Gravitational Waves in Palatini Chern-Simons
Felipe Sulantay, Macarena Lagos, Máximo Bañados
We study the parity-breaking higher-curvature gravity theory of Chern-Simons (CS), using the Palatini formulation in which the metric and connection are taken to be independent fie…
Nonlinearities in Black Hole Ringdowns
Keefe Mitman, Macarena Lagos, Leo C. Stein +11
The gravitational wave strain emitted by a perturbed black hole (BH) ringing down is typically modeled analytically using first-order BH perturbation theory. In this Letter we show…
Generation and propagation of nonlinear quasi-normal modes of a Schwarzschild black hole
Macarena Lagos, Lam Hui
In the analysis of a binary black hole coalescence, it is necessary to include gravitational self-interactions in order to describe the transition of the gravitational wave signal…
New Horizons for Fundamental Physics with LISA
K. G. Arun, Enis Belgacem, Robert Benkel +138
The Laser Interferometer Space Antenna (LISA) has the potential to reveal wonders about the fundamental theory of nature at play in the extreme gravity regime, where the gravitatio…
Cosmology with the Laser Interferometer Space Antenna
Pierre Auclair, David Bacon, Tessa Baker +177
The Laser Interferometer Space Antenna (LISA) has two scientific objectives of cosmological focus: to probe the expansion rate of the universe, and to understand stochastic gravita…
Modified gravitational wave propagation with higher modes and its degeneracies with lensing
Jose Maria Ezquiaga, Wayne Hu, Macarena Lagos +2
Low-energy alternatives to General Relativity (GR) generically modify the phase of gravitational waves (GWs) during their propagation. As detector sensitivities increase, it become…
