The morphology, star-formation history, dynamics, and many other properties of galaxies depend strongly on where they formed and where they live. In other words, galaxies are affected by their environment. We have already studied in great detail the most extreme environments (cores of rich galaxy clusters), but milder environments such as the groups and the filamentary structures that feed galaxy clusters remain largely unexplored. We know that these environments must play an important role on galaxy evolution because many of the galaxies that fall into clusters have already been "pre-processed" by the time they arrive to the cluster core. In this project we will combine state-of-the-art numerical galaxy formation and evolution models with new and unique observational data taken with some of the most innovative astronomical instruments to, first, map these structures and identify the galaxies that inhabit them and, second, study their properties to find out how these environments affect their history.

星系的形态、恒星形成历史、动力学和许多其他性质强烈地依赖于它们在哪里形成和生活在哪里。换句话说，星系受其所处环境的影响。我们已经非常详细地研究了最极端的环境(丰富星系团的核心)，但较温和的环境，如星系团和滋养星系团的丝状结构，基本上仍未被探索。我们知道，这些环境肯定对星系演化起着重要作用，因为许多落入星系团的星系在到达星系团核心时已经经过了“前处理”。在这个项目中，我们将把最先进的数字星系形成和演化模型与一些最具创新性的天文仪器获取的新的和独特的观测数据结合起来，首先绘制这些结构并识别其中的星系，然后研究它们的性质，找出这些环境如何影响它们的历史。
