Notes on gravitational wave amplitude evolution beyond null geodesics
Charles Dalang
In these notes, we extend a formalism for computing the amplitude of gravitational-waves (GWs) beyond null-geodesic propagation, as may arise in alternative theories of gravity. We…
Large scale structure prior knowledge in the dark siren method
Charles Dalang, Bartolomeo Fiorini, Tessa Baker
Gravitational wave dark sirens are a powerful tool for cosmology and inference of compact object population hyperparameters. They allow for a measurement of the luminosity distance…
Multi-messenger lensing time delay as a probe of the graviton mass
Elena Colangeli, Charles Dalang, Tessa Baker
Gravitational lensing is a powerful probe of cosmology and astrophysics. With the prospect of the first strongly lensed gravitational waves on the horizon, we highlight an opportun…
First measurement of the Hubble constant from gravitational wave-galaxy cross-correlations
Isabela Santiago de Matos, Charles Dalang, Tessa Baker +4
We measure for the first time the Hubble constant () from the cross-correlation of galaxies and gravitational waves (GW), by applying the method. This m…
Redshift tomography of the kinematic matter dipole
Sebastian von Hausegger, Charles Dalang
The dipole anisotropy induced by our peculiar motion in the sky distribution of cosmologically distant sources is an important consistency test of the standard FLRW cosmology. In t…
