Study of the weak lensing in galaxy clusters with LSST

Starting in 2023 and for a duration of ten years the Large Synoptic Survey Telescope (LSST) project will perform an optical survey of the whole sky visible from a site in Chile using a large-field telescope equipped with a 3.2 billion pixel camera. This survey will allow to create a wide and deep mapping of the distribution of galaxies in the universe.

Galaxy clusters are the largest gravitationally bound structures in the universe. Their study, in particular the estimation of the number of clusters as a function of their mass and redshift, gives important information on the growth of the structures in the universe. From this measurement we can deduce constraints on the cosmological parameters as well as on the validity of various modified gravitation models. Large astronomical surveys in the optical domain such as LSST will allow to measure tens of thousands of galaxy clusters and thus bring this cosmological probe to a level of precision never reached before.
