Welcome on the pages of the Cosmology team !
Our research reaches from the primordial fluctuations in the Universe down to its structuration at the largest scales in the most recent era. We study how the cosmic web elements are forming and evolving both through modelling and observations.

Hubert Bretonnière, Cosmology team, defended his thesis entitled "Galaxy morphology for Euclid: Simulations, forecasts and detection with deep learning", carried out under the supervision of Hervé Dole, Marc Huertas-Company, and Alexandre Boucaud. He is now a new doctor of Université Paris Saclay and is leaving for the University of Santa Cruz (USA). Congratulations to him!
The first data were presented on Tuesday 12 July. They confirm the exceptional performance of the JWST and its four scientific instruments (NIRSPec, NIRISS, NIRCam, MIRI), in particular the angular resolution and sensitivity which are often better than predicted.
For the first time, taking advantage of innovative artificial intelligence methods, an IAS team has discovered thousands of galaxy clusters in Planck satellite observations, published in a new catalogue.
The environmental and performance test campaign of the flight model of the Euclid mission Payload Module (PLM), performed at Airbus Defence and Space (Toulouse, France), ended successfully in September 2021. The results of the test campaign show that both the VIS and NISP instruments are working to specifications.
A galaxy protocluster dating from when the Universe was the most active in star formation has been discovered. It forms many stars at a pace not reproduced by current models, and it will eventually evolve into a superstructure.
