Euclid space mission: a cosmological challenge for the next 15 years

Understand

Euclid is the next ESA mission devoted to cosmology.

• It aims at observing most of the extragalactic sky, studying both gravitational lensing and clustering over $\sim$15,000 square degrees.
• The mission is expected to be launched in year 2020 and to last six years.
• The sheer amount of data of different kinds, the variety of (un)known systematic effects and the complexity of measures require efforts both in sophisticated simulations and techniques of data analysis.
