Presentation

The Cosmology team addresses two major themes of the field: the physical laws that govern the Universe, and the formation and evolution of the Universe. The activities of the Cosmology team are articulated around a continuum of physical problems related to the structuration of matter from the largest scales of the Cosmic Microwave Background (CMB) down to the scales of galaxies. They draw on modelling, simulations, theoretical and observational approaches.

A special effort is being conducted for the development of tools for data processing and analysis, as well as for the distribution of products and reference softwares to the community. In parallel, we conduct multidisciplinary R&D in the field of bolometers, including bolometer arrays for future projects.

Our instrumental developments are done in the context of the space- and ground-based programmes of the discipline. We were PI of the Planck/HFI. We had and have commitments in instrumental contributions or ground segments for ISO, XMM-Newton, Herschel, EUCLID (M2 ESA Mission), PILOT (CNES balloon-borne experiment), PRONAOS (CNES balloon-borne experiment), NIKA (instrument for the 30m telescope of IRAM), ATHENA (L2 ESA Mission). We are involved in the development of LiteBIRD (JAXA) as futur satellite of the CMB, as well as leading the BISOU balloon project (CNES) as pathfinder for futur spectral distorsion experiments.
