Abstract

Clusters of galaxies are the largest organised structures in the Universe that are gravitationally bound, containing thousands of galaxies all confined to a volume of space only tens of millions of light years across. They are laboratories for extreme galaxy evolution, as many of the processes that can change the structure of galaxies are accelerated in such a crowded environment. Clusters of galaxies also provide important constraints for cosmology: from both the way they are grouped into superclusters that trace the ‘large scale structure’ of Universe; and the fact that their internal properties lead to powerful confirmation for the need for dark matter and dark energy.
