Testing local isotropy with weak lensing

Jean-Philippe Uzan, IAP Paris

Spatial local isotropy is one of the properties that undelines the Copernican principle which plays a central role in the construction of the standard cosmological model. I will recall the formulation of this principle and summarize its implications. I will then describe a test based on weak lensing observations, that I recently proposed in collaboration with Cyril Pitrou and Thiago Pereira and that hopefully can be implemented with the Euclid observations.
