Most galaxies in the Universe live in groups or clusters, making such large-scale structure critical both for studies of cosmology and of galaxy evolution. This project builds on a successful research program working at the interface between simulations and observations to understand the physical processes that influence these objects and the galaxies inhabiting them. Students will exploit state-of-the-art N-body and hydrodynamic simulations, galaxy evolution models, and large imaging and spectrographic surveys to study the properties of large scale structure in both the real and mock universes. Comparison of both approaches allows us to simultaneously test the model physics, gain insight into the data, and understand the ultimate limitations of our measurements. Our goals include understanding group and cluster assembly (and implications for large cosmological surveys) as well as distentangling the interplay between galaxy properties and their environments.

宇宙中的大多数星系都以群体或星系团的形式存在，使得如此大规模的结构对于宇宙学和星系演化的研究都至关重要。该项目建立在一个成功的研究计划的基础上，该研究计划致力于模拟和观测之间的接口，以了解影响这些天体及其居住星系的物理过程。学生将利用最先进的 N 体和流体动力学模拟、星系演化模型以及大型成像和光谱测量来研究真实和模拟宇宙中大规模结构的特性。两种方法的比较使我们能够同时测试模型物理、深入了解数据并了解测量的最终局限性。我们的目标包括了解星系团和星团的组装（以及对大型宇宙学调查的影响）以及解开星系属性与其环境之间的相互作用。
