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

TL;DR

Euclid is a forthcoming ESA space mission focused on cosmology, aiming to map a large portion of the sky to study gravitational lensing and galaxy clustering, which will challenge data analysis and simulation techniques over the next 15 years.

Contribution

This paper reviews Euclid's mission design, survey scope, and key scientific challenges, emphasizing the need for advanced simulations and data analysis methods.

Findings

Euclid will observe ~15,000 square degrees of extragalactic sky.

The mission will generate large, complex datasets requiring sophisticated analysis.

Systematic effects and data variety pose significant challenges for cosmological measurements.

Abstract

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. We review the mission main characteristics, some aspects of the the survey and highlight some of the areas of interest to this meeting
