Cosmology - C. Payerne (IRFU CEA, Saclay, FR) - Cosmology with galaxy clusters in the Rubin LSST era

Galaxy clusters are among the main cosmological tracers for probing the late-time universe, offering unique insight into how cosmic structure grows and what drives it, from dark matter to dark energy. With next-generation photometric surveys like the Vera C. Rubin Observatory’s LSST and Euclid set to deliver hundreds of thousands of optically selected clusters, we are entering an era of unpreceden
