Theoretical and numerical perspectives on cosmic distance averages
Michel-Andrès Breton, Pierre Fleury
The interpretation of cosmological observations relies on a notion of an average Universe, which is usually considered as the homogeneous and isotropic Friedmann-Lemaître-Robertson…
Gravitational lenses in arbitrary space-times
Pierre Fleury, Julien Larena, Jean-Philippe Uzan
The precision reached by current and forthcoming strong-lensing observations requires to accurately model various perturbations to the main deflector. Hitherto, theoretical models…
Scalar and tensor gravitational waves
Charles Dalang, Pierre Fleury, Lucas Lombriser
In dark-energy models where a scalar field is nonminimally coupled to the spacetime geometry, gravitational waves are expected to be supplemented with a scalar mode. Such scalar wa…
A null test of the equivalence principle using relativistic effects in galaxy surveys
Camille Bonvin, Felipe Oliveira Franco, Pierre Fleury
The weak equivalence principle is one of the cornerstone of general relativity. Its validity has been tested with impressive precision in the Solar System, with experiments involvi…
