Evolution of the galaxy-halo connection across times

这个项目是在一系列新的星系调查中对星系晕联系的调查，最初的重点是PAUS在中间红移的窄带调查，可能会随着MOONS的调查而转向更高的红移。这扩展了以前的分析，在较低的红移与GAMA进行了更深入的研究，在更高的红移，通过采样一个更均匀的方式明显更大的体积。该项目需要开发一种新的基于马尔可夫聚类的群体查找器，当应用于具有典型星系数密度的样本时，该算法已被证明优于标准的“朋友的朋友”算法。结果将是更好地理解星系是如何填充和晕的，目的是提高对星系如何形成和演化的认识。

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.
