Testing Cosmology with Weak Lensing Surveys
Weak lensing measurements by the Dark Energy Survey (DES) and the new generation of wide field galaxy surveys offer an exciting window on the properties and laws of the Universe. In this talk, I will describe our approach to constrain non-standard cosmological models with the latest DES weak lensing data. I will then give my perspective on the lessons learnt and challenges for future tests, especially with the Rubin Observatory. I will end by presenting a new approach I proposed to overcome one of these challenges and maximize the potential for discovery of new physics in the coming decade.
