Euclid is an ESA mission to map the large-scale structure of the Universe over a large portion of the extragalactic sky (part of the sky not dominated by the stars in our Milky Way). To achieve this, a satellite equipped with a 1.2 m telescope and three imaging and spectroscopic instruments working in the visible and near-infrared wavelength domains has been proposed. It will measure shapes and redshifts of galaxies and clusters of galaxies out to redshifts ~2, or equivalently it will look-back time of 10 billion years. Correlations in the galaxy shapes will be used to measure the effects of gravitational lensing, while redshifts are used to infer distances and map the galaxy distribution. The Euclid survey can be thought of as the low-redshift, 3-dimensional analogue and complement to the map of the high-redshift Universe provided by ESA's Planck mission, but using the large-scale structure traced by galaxies instead of the fossil CMB radiation. The satellite will be launched in 2020 by a Soyuz ST-2.1B rocket and transferred to the L2 Lagrange point for a 6-year mission. [+]


ICCUB contribution to the EUCLID mission is nowadays made through the individual contribution of ICCUB researchers Licia Verde and Cristiano Germani, who are part of the Science Working Group.
