Description

Euclid is an ESA-led medium class space mission selected in October 2011, with contributions from NASA, whose launch took place in July 2023. The Euclid mission aims to set some light on the nature of Dark Matter, which makes up to 27% of the energy content of the universe, and Dark Energy, which corresponding to approximately 70% and we believe is the responsible of the current accelerated expansion of the Universe. With these goals in mind, the Euclid mission expects to generate the most robust (and largest) 3D-map of the universe by observing 1/3 of the sky. To infer the nature of Dark Energy and Dark Matter Euclid data will be compared to cosmological models using two complementary cosmological probes: weak lensing; and galaxy clustering. In this talk, I will explain the status of the Euclid mission since its launch, its main science goals, the structure of the Euclid Consortium, how we construct the theoretical predictions of the primary observables, and I will show forecasts of cosmological parameters.
