Our group is involved in several area of research in cosmology. The bulk of the activity is dedicated to the quest for Dark Energy in the Universe and the study of the cosmic structure formation. Our approach make use of both analytical and numerical methods. Topics of interest concern the modeling of non-linear structure formation processes, the formulation of Dark Energy and Modified Gravity models, fundamental tests of Inflation, physics of the Cosmic Microwave Background and Bayesian statistical data analysis methods.
A veritable team effort is devoted to the realization of large volume high-resolution numerical simulations. Our group is one of the main users of super-computing facilities in France and Europe with access to tier-1 and tier-0 machine. This intense activity is organized in a number of projects:
The group also participates to the science support and simulation working group of two observational projects:
