Group Evolution Multiwavelength Study

The GEMS project is a collaboration involving groups at Birmingham, Liverpool John Moores, Melbourne, Nottingham, Sussex and Swinburne Universities. Our aim is to combine data taken in a variety of wavebands, to study the properties of galaxy groups and the galaxies within them. Comparing these properties with cosmological simulations and evolutionary models, will improve our understanding of the way in which galaxies evolve within the environment in which they are most commonly found.
