Webpage: Euclid Consortium A space mission to map the Dark Universe
Euclid is an ESA mission to map the geometry of the dark Universe. The mission will investigate the distance-redshift relationship and the evolution of cosmic structures by measuring shapes and redshifts of galaxies and clusters of galaxies out to redshifts ~2, or equivalently to a look-back time of 10 billion years. In this way, Euclid will cover the entire period over which dark energy played a significant role in accelerating the expansion.
Members of IPARCOS participate in the Theory Working Group. This group proposes and selects cosmological models and analyses fundamental physics aspects that will be tested by the mission.
