The cosmic web, in its many facets, is known to shape galaxy
evolution. It is a fundamental task to understand how and when the
various components of the cosmic web, still in formation, began to
affect galaxies' life. WST capabilities will be crucial in shading
light in this context. I will briefly review some of the open
questions related to the many component of the cosmic web, and...
Ongoing and upcoming wide-field imaging campaigns, such as the Euclid Wide and Deep Surveys and Rubin Observatory’s LSST, will enable measurements of the photometric and structural properties of tens of millions of galaxies, spanning the local Universe to redshifts of 2–3 and beyond, from dwarfs to the most massive galaxies. In particular, Euclid will uncover hundreds of thousands of dwarf...
We present a potential science case for the WST facility, focusing on the detailed characterisation of galaxy stellar populations as a function of the environment. This builds on the analysis we performed on a restricted sample of massive quiescent galaxies in the COSMOS Wall structure at z = 0.73. This structure encompasses a diverse range of environments, from rich and dense clusters to...
The existence of filaments connecting galaxies, within which galaxies form, has been a long-standing prediction of structure formation theories in a Universe dominated by cold dark matter. However, direct imaging of these filaments has remained elusive until the advent of large-format integral field spectrographs such as the Multi Unit Spectroscopic Explorer (MUSE) at the Very Large...
