Euclid is an Stage IV ESA mission whose main target is the study of arguably the largest mystery of current physics: the nature of Dark Energy (DE). For this purpose, it plans to use both geometrical and dynamical probes. The former are essentially relying on the measurement of 2D and 3D baryonic acoustic oscillations (BAO) from the photometric and spectroscopic galaxy samples, while the latter are mostly based on the measurement of redshift space distortions in the spectroscopic sample, plus the abundance of galaxy clusters at high redshifts. But it must be stressed that Euclid is much more than a Dark Energy survey. Its unprecedented image quality, depth and systematics control should allow constraining other key cosmological parameters related to the inflationary epoch (f_NL, g_NL), the total mass of neutrinos, together with alternative gravity theories. Its data should shed more light on the elusive nature of dark matter, and will provide an uncomparable data set (both in quality and volume) that will surely impact practically all disciplines of Astrophysics, ranging from sub-stellar objects in the Milky Way up to the epoch of the dark ages and the end of the epoch of Cosmological Reionization.
In this talk we shall briefly describe the contribution of the different groups that are participating in this mission from the IAC.
