The cosmoIGM proposal aims at investigating the role of the Intergalactic Medium (IGM) as a cosmological probe and at exploiting the many IGM-related sinergies between observational cosmology, galaxy formation and fundamental physics. The IGM is a unique cosmological observable as it probes 3/4 of the present age of the universe, it contains up to 80% of the baryons and is sensitive to scales th ...

The observed properties of galaxies have long been known to depend on the environment in which they are located. The physical origin of the observed environmental trends is, however, still a subject of debate. Much of the argument centres on whether these trends are the end products of physical processes acting over the entire lifetime of a galaxy (the nurture hypothesis), or whether they are esta ...
