If you have a question about this talk, please contact scott chapman.

A key question concerning the evolution of galaxies within the concordance cosmological framework is how this evolution is modulated by the broader environment of a galaxy, i.e. the interaction of galaxies with their dark matter haloes, and the location of galaxies within the cosmic web of large-scale filaments and voids in the Universe. I will present new results from an observational survey of galaxies in groups on the dependence of galaxy properties on halo mass and large-scale environmental density, and a comparison with hydrodynamical numerical simulations that guide us towards an understanding of the physical processes that shape the galaxy population that we observe today.
