The Large Scale Structure in Cosmology is represented by the formation, evolution and statistics of density perturbations, from cluster of galaxies to the largest observable scales reaching billions of light years.
My group at SISSA is involved in one
of the main global efforts for measuring cosmological structures
, directly and in cross-correlation with the Cosmic Microwave Background and Gravitational Waves, mainly in order to investigate the Dark Energy and Matter
. See here for more detailed information available at SISSA.
