This project is an investigation of the galaxy halo connection in a series of novel galaxy surveys, initially focusing on the PAUS narrow band survey at intermediate redshifts, and possibly moving to higher redshifts with the MOONS survey. This extend previous analyses done at lower redshifts with GAMA by going significantly deeper and at higher redshifts by sampling a significantly larger volume in a more homogenous fashion. The project requires the development of a new group finder based on Markov Clustering that has been shown to outperform standard friends-of-friends algorithms when applied to samples with typical galaxy number densities. The outcome will be a better understanding of how galaxies populate and halos, with the aim of improving of knowledge of how galaxies form and evolve.

该项目是一系列新星系巡天中星系晕连接的调查，最初集中在中等红移的PAUS窄带巡天，并可能与MOONS巡天一起移动到更高的红移。这扩展了以前的分析，在较低的红移与GAMA去显着更深，并在更高的红移采样显着更大的体积在一个更均匀的方式。该项目需要开发一种基于马尔可夫聚类的新的组查找器，该算法在应用于具有典型星系数密度的样本时，表现优于标准的朋友的朋友算法。其结果将是更好地了解星系如何居住和晕，目的是提高星系如何形成和演变的知识。
