Description
Euclid is a European Space Agency telescope designed to map the dark Universe and uncover the nature of cosmic acceleration. It is conducting a large survey of galaxies, which will be used to measure the large-scale mass distribution of the Universe through weak gravitational lensing, galaxy clustering, and their combination ('3x2pt'). I will explain how we plan to use Euclid's imaging to constrain cosmological models and describe specific challenges that must be overcome to deliver precise results. I will place Euclid in the context of other existing/planned observational cosmology programmes, and discuss how Euclid might influence the landscape of viable cosmological models and cast light upon current tensions in Lambda-CDM.
