WebGalaxy Groups form through the merger of individual galaxies. Groups then come together to form larger groups and clusters, which in turn merge to form large-scale filaments, … Web12 de jan. de 2007 · In hierarchical models, ‘a galaxy’ should not be viewed as a single object evolving in time, but rather as the ensemble of its progenitors at each given time. In this section, we focus on a single model BCG and describe the formation and assembly history of its stars in detail.
