Abstract Upcoming galaxy and CMB surveys, including LSST and CMB-S4, are an unprecedented opportunity to explore the dark sector of the Universe. By mapping the distribution and shape of billions of galaxies, and by reconstructing the CMB gravitational lensing induced by large scale structures, these experiments offer complementary observables that shed light on the matter distribution and the growth of cosmic structures. This research project aims to develop the cross correlation and joint analysis of the LSST galaxy survey with CMB experiments, such as CMB-S4. By leveraging the synergies between these probes, we can overcome systematic limitations and break parameter degeneracies, enabling optimal constraints on key parameters such as the equation of state of dark energy and the sum of neutrino masses.
