European Network: The Formation and Evolution of Galaxies - Our goal is to understand how galaxies formed and how the Universe has evolved over the last 90 percent of its history. The program will study distant galaxies at optical, infrared, and radio frequencies. In addition it will be coupled to theoretical work on protogalactic collapse, on galaxy evolution, and on the interaction of galaxies with their environment.
