The Astrophysics of the Large-Scale Structures in the era of eROSITA, Euclid, SPT-3G: the emergence of the Cosmic Web
IFPU
8-12 September 2025
Most of the Universe is still invisible, with 95% of its contents consisting of dark matter and dark energy yet to be understood. But even the remaining 5% in the form of ordinary matter, which has been mostly heated by strong structure formation shocks, resides in a largely unexplored hot, diffuse, X-ray emitting plasma that permeates the halos of galaxies, galaxy groups and clusters, and the cosmic web as defined by the intricate network of filaments, nodes, and sheets generated by the interaction of gravity and the dark components. This program seeks to initiate an exploration of these large-scale cosmic structures with a variegate approach that tries to combine, in an effective and exhaustive way, observations, simulations and models. Specifically, we will focus on the environment in which collapsed objects exceeding 1e13 solar masses and existing up to redshift 2 form and evolve. Gathering together world-wide recognized experts in the field, we plan (i) to present the best dataset available from optical, IR, X-ray, SZ facilities, and state-of-the-art hydrodynamical simulations, (ii) to discuss the interconnections among these different proxies in providing a consistent and coherent picture of the backbone of the universe, (iii) to promote synergetic activities to further advance our understanding of the astrophysical phenomena behind the formation and evolution of the cosmic structures.
