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.

Stefano Gallo, Cosmology team, defended his thesis entitled ‘On Galaxy Cluster modelling in the context of Cosmological analyses’, under the supervision of Nabila Aghanim and Marian Douspis. He is now a new doctor at the Université Paris-Saclay, and will be heading for Germany. Congratulations to him!
On May 28, CNES has officially confirmed the balloon-borne project BISOU for Phase A. The study will be carried out over the next two years and marks a transformational step towards an ambitious space-borne CMB spectrometer in the ESA Voyage 2050 program.
As part of its programme, carried out over several years, to study the effects of cosmic rays effects on highly sensitivity cryogenic detectors, the IAS has developed the DRACuLA (Detector irRAdiation Cryogenic faciLity for Astrophysics) system for measuring the response of this type of detector to the impact of particles such as protons or alpha particles.
The first scientific results from Euclid, the European space cosmology mission, were unveiled on Thursday May 23, 2024: 15 scientific papers, including 5 general ones about the space mission, its instruments and processing, and 10 on the first astrophysical observations. These first observations and articles confirm Euclid's performances, and mark the start of the “Euclid era” for cosmology. The nominal mission will last 6 years, with partial data delivery within 1 year, and the first data delivery within 2 years.
Euclid’s two instruments have captured their first test images. The mesmerising results indicate that the space telescope will achieve the scientific goals that it has been designed for – and possibly much more.
Although there are months to go before Euclid delivers its true new view of the cosmos, reaching this milestone means the scientists and engineers behind the mission are confident that the telescope and instruments are working well.
