项目摘要
New telescope facilities and dedicated surveys have resulted in enormous progress in extra-galactic astronomy and cosmology over the past two decades. While we have now tightly constrained many of the fundamental cosmological parameters that describe our universe, there are still many unanswered questions concerning the formation and evolution of galaxies and larger structures. My research team is interested in studying the assembly of galaxies and the connection between observed galaxies and their environments. In order to address these topics we will study the evolution of galaxies in galaxy groups and clusters as a function of cosmic time.****Most galaxies in the local universe do not live in isolation, but are clustered into systems called galaxy groups. This environment, intermediate in density between rich galaxy clusters and isolated galaxies, appears to play an important role in galaxy evolution. However, relatively few sizable samples of groups have been identified at large distances. Over the past few years my team has been actively engaged in studying a large sample of groups at intermediate distances in order to understand the role that this environment plays in the evolution of galaxies. We have learned that the observed properties of group member galaxies depend on the group environment in which we find them, but that environmental effects are subtle and require large samples and careful analysis. In particular we have found that the properties of galaxies in groups depend on the assembly history of their host group, which can be traced using the motions of observed member galaxies. ****Over the next five years I plan to work with my students to study the evolution of more distant group galaxies from an epoch when the universe was much younger and many systems were just forming. Our goal is to shed light on the physical mechanisms governing the evolution of galaxies over cosmic time. We hope to further understand the diversity of galaxies and their properties and how their host environments affects this diversity. To answer these questions we will push the limits of current astronomical observations and plan for surveys with the next generation of facilities.**
在过去二十年中,新的望远镜设施和专门的调查使银河系外天文学和宇宙学取得了巨大进展。虽然我们现在已经严格限制了许多描述我们宇宙的基本宇宙学参数,但关于星系和更大结构的形成和演化仍然有许多未解之谜。我的研究团队对研究星系的组装以及观测星系与其环境之间的联系感兴趣。为了解决这些问题,我们将研究星系群和星系团中星系的演化作为宇宙时间的函数。本星系中的大多数星系并不是孤立存在的,而是聚集在称为星系群的系统中。这种环境的密度介于富裕星系团和孤立星系之间,似乎在星系演化中发挥着重要作用。然而,在远距离上识别出的相当大的群体样本相对较少。在过去的几年里,我的团队一直在积极地研究中距离星系群的大样本,以了解这种环境在星系演化中所起的作用。我们已经了解到,星系群成员星系的观测特性取决于我们发现它们的星系群环境,但环境影响是微妙的,需要大量的样本和仔细的分析。特别是,我们已经发现,星系群中的属性取决于其主机组的组装历史,这可以跟踪使用观察到的成员星系的运动。* 在接下来的五年里,我计划和我的学生一起研究更遥远的星系群的演化,从宇宙更年轻的时代开始,许多系统刚刚形成。我们的目标是阐明在宇宙时间内控制星系演化的物理机制。我们希望进一步了解星系的多样性及其特性,以及它们的宿主环境如何影响这种多样性。为了回答这些问题,我们将突破目前天文观测的极限,并计划用下一代设施进行调查。
