Collaborative Research: A Holistic Approach to Modeling Galaxy Clusters

该团队将对大范围质量的星系团进行大量最先进的模拟。这些模拟将结合恒星形成和超大质量黑洞反馈的观测约束模型，以及对化学演化的新处理。目的有两个：(1)建立星系、超大质量黑洞和星系团内高温气体演化的统一描述；(2)确定制约星系反馈过程与宇宙结构增长之间相互作用的关键可观测特征。这些努力构成了一种自洽的、整体的反馈方法，能够解释在所有质量尺度上观察到的多方面特性。该团队将继续参与一个已建立的、成功的STEM项目。这项研究将增加模拟的物理真实性，增加向公众发布的图像产品的吸引力。

The team will perform numerous state-of-the-art simulations of galaxy clusters spanning a large range inmass. The simulations will incorporate observationally-constrainedmodels for feedback from star formation and supermassive black holes,along with a novel treatment of chemical evolution. Theaims are twofold: (1) Establish a unified description for theevolution of the galaxies, the supermassive black holes, and the hottenuous gas within the clusters; (2) Determine the key observablesignatures that constrain the interplay between the processes ofgalaxy feedback and the growth of structure in the Universe. Theseefforts constitute a self-consistent, holistic approach to feedback that will be able to account for multifacetedproperties observed across all mass scales. The team will continue itsinvolvement in an established, successful STEM program. The researchwill increase the physical realism of the simulations, increasing theappeal of the image products released to the public.
