From 15 to 17 November, around 30 scientists working in cosmological simulations for the ESA Euclid space mission gathered at the Institute of Space Sciences (ICE-CSIC). The workshop’s goal was to discuss the plans to prepare the simulations that will be used for the first Data Release of the Euclid mission (DR1).

The ESA space mission Euclid, launched into space on July 1st, just released its first full-colour images - the sharpest ones ever across such a large patch of the sky and looking so far into the distant Universe. In the months after launch, Euclid’s scientists have been doing the last fine-tuning of the spacecraft before routine science observations begin in early 2024.

Euclid will create the largest and most accurate 3D map of the universe to study the dark universe. Therefore, it will help us understand the nature of dark matter and energy which, according to the latest studies, make up around 95% of the matter and energy content in the universe.

“In order to exploit these exquisite data sets, we need to develop very realistic simulations that mimic the large volume and complexity of the real data that Euclid will provide. The meeting we had this week at ICE-CSIC has been very useful to discuss the plans to prepare the simulations that shall be used for the first Data Release of the mission,”  says ICE-CSIC and IEEC researcher Pablo Fosalba.

ICE-CSIC, together with the Institute for Space Studies of Catalonia (IEEC) and the Institute of High Energy Physics (IFAE), have worked for more than 11 years on this mission and have been responsible for the design, construction, assembly and validation tests of the Filter Wheel Assembly (FWA) of the NISP instrument and for generating cosmological simulations that have served to study its optimization and prepare the software for data processing and analysis.
