Collaborative Research: Galaxies within Clusters: A New Dark Energy Probe

这项合作计划将开发和实施一项新技术，用于测量星系团暗物质结构的增长。虽然大多数使用星系聚集来限制宇宙学参数的技术都集中在最大尺度上的测量，但研究人员的目标是在最小尺度上使用聚集，充分利用数据中可用的信息，目标是开发一种新的宇宙学探测器，该探测器基于星系和暗物质晕之间的关系，可以应用于现有数据和未来的调查。这种方法可能会发展成为下一代光度测量中对暗能量和其他宇宙学参数的领先探测。这项工作的广泛影响包括对研究生的培训，向社区发布计算机代码，以及通过公开讲座进行推广。

This collaborative program will develop and implement a new technique for measuring the growth of dark matter structure from galaxy clustering. While most techniques that use galaxy clustering to constrain cosmological parameters focus on measurements at the largest scales, the investigators aim to use clustering at the smallest scales, making full use of the information available in the data with the goal of developing a new cosmological probe based on the relationship between galaxies and dark matter halos that can be applied to existing data and future surveys. This approach could develop into a leading probe of dark energy and other cosmological parameters with the next generation of photometric surveys.Broader impacts of the work include training of graduate students, release of computer code to the community, and outreach via public lectures.
