Weak lensing distortions beyond shear
Pierre Fleury, Julien Larena, Jean-Philippe Uzan
When a luminous source is extended, its distortions by weak gravitational lensing are richer than a mere combination of magnification and shear. In a recent work, we proposed an el…
Cosmic convergence and shear with extended sources
Pierre Fleury, Julien Larena, Jean-Philippe Uzan
The standard theory of weak gravitational lensing relies on the approximation that light beams are infinitesimal. Our recent work showed that the finite size of sources, and the as…
Testing the equivalence principle on cosmological scales
Camille Bonvin, Pierre Fleury
The equivalence principle, that is one of the main pillars of general relativity, is very well tested in the Solar system; however, its validity is more uncertain on cosmological s…
