Abstract

Euclid is the next ESA mission devoted to Cosmology. The mission is expected to be launched in year 2020 and to last six years. The payload comprises two instruments, provided by the Euclid Consortium. Both have wide field capabilities hosting a visible and a near infrared camera, respectively, which cover a joint field of view of half square degree. The NIR instrument is also capable of slitless spectroscopy.

The main scientific aim is the study of Dark Energy and Dark Matter. These will be studied via gravitational lensing and clustering over ~15000 square degrees. Since this area will cover most of the extragalactic sky, the wealth of data data will be extremely valuable to several areas in astrophysics. Indeed, the sheer amount of data of different kinds, the variety of (un)known systematic effects and the complexity of measures require novel efforts both in simulations and techniques of data analysis.
