Aberration of gravitational waveforms by peculiar velocity
Camille Bonvin, Giulia Cusin, Cyril Pitrou +3
One key prediction of General Relativity is that gravitational waves are emitted with a pure spin-2 polarisation. Any extra polarisation mode, spin-1 or spin-0, is consequently con…
Detection and estimation of the cosmic dipole with the Einstein Telescope and Cosmic Explorer
S. Mastrogiovanni, C. Bonvin, G. Cusin +1
One of the open issues of the standard cosmological model is the value of the cosmic dipole measured from the Cosmic Microwave Background (CMB), as well as from the number count of…
Combining gravitational lensing and gravitational redshift to measure the anisotropic stress with future galaxy surveys
Isaac Tutusaus, Daniel Sobral-Blanco, Camille Bonvin
Galaxy surveys provide one of the best ways to constrain the theory of gravity at cosmological scales. They can be used to constrain the two gravitational potentials encoding time,…
Modified Einstein versus Modified Euler for Dark Matter
Camille Bonvin, Levon Pogosian
Modifications of General Relativity generically contain additional degrees of freedom that can mediate forces between matter particles. One of the common manifestations of a fifth…
Model-Independent Test for Gravity using Intensity Mapping and Galaxy Clustering
Muntazir M. Abidi, Camille Bonvin, Mona Jalilvand +1
We propose a novel method to measure the statistic from clustering alone. The statistic provides an elegant way of testing the consistency of General Relativity by comp…
Measuring the distortion of time with relativistic effects in large-scale structure
Daniel Sobral-Blanco, Camille Bonvin
To test the theory of gravity one needs to test, on one hand, how space and time are distorted by matter and, on the other hand, how matter moves in a distorted space-time. Current…
