Exploring the Dark Universe

Euclid is an ESA mission to map the geometry of the Universe and better understand the mysterious dark matter and dark energy, which make up most of the energy budget of the cosmos. The mission will investigate the distance-redshift relationship and the evolution of cosmic structures by measuring shapes and redshifts of galaxies and clusters of galaxies out to redshifts ~2, or equivalently to a look-back time of 10 billion years. In this way, Euclid will cover the entire period over which dark energy played a significant role in accelerating the expansion of the Universe.


An ESA mission to understand dark matter and dark energy

Euclid is an ESA medium class space mission, which aims at understanding why the expansion of the universe is accelerating and the cause for this acceleration which physicists refer to as dark energy. Euclid will explore how the Universe evolved over the past 10 billion years to address questions related to fundamental physics and cosmology on the nature and properties of dark energy, dark matter and gravity. Euclid will also provide insightful information on the physics of the early universe and on the initial conditions which seed the formation of cosmic structure.

ICE-CSIC's participation

ICE-CSIC is deeply involved in the Euclid mission. We form part of the Euclid Science Team of the mission. We are members of the Euclid Consortium Board. We are responsible, together with IFAE, of delivering the Filter Wheel Assembly (FWA) of the Near Infrared Spectrograph and Photometer (NISP). We lead the Simulation Organization Unit and are deputy coordinators of the Photometric Redshift Organization Unit of the Science Ground Segment. We lead the Cosmological Simulations Science Working Group and actively participate as well in other Science Working Groups.
