Speaker
Description
Galaxy clusters are the most massive gravitationally bound structures in the Universe, sitting at the crossroads between galaxy evolution and cosmology, and providing fundamental information about the composition and evolution of the Universe. This plenary talk will summarise recent results from large multi-wavelength surveys and our current understanding of cluster abundances, galaxy properties and scaling relations in clusters, as well as cluster dynamics over cosmic time, using some of the best facilities such as eROSITA in X-rays, JWST in optical/NIR, or MeerKAT in radio, among others. The talk will conclude with a summary of the main open questions and the opportunities offered by next-generation telescopes to use galaxy clusters as both cosmic probes and astrophysical laboratories.
