论文摘要
银河红移调查是现代宇宙学的关键探针之一。在银河调查的数据分析中，统计测量的精度主要受到大规模的宇宙差异的限制。幸运的是，可以通过观察多种偏见的示踪剂来避免这种限制。在这篇简短的评论中，我们介绍了多跟踪方法的想法，概述了数据分析中的关键步骤，并根据GAMA，BOSS和EBOSS GALAXY调查显示了几个工作示例。
Galaxy redshift surveys are one of the key probes in modern cosmology. In the data analysis of galaxy surveys, the precision of the statistical measurement is primarily limited by the cosmic variance on large scales. Fortunately, this limitation can in principle be evaded by observing multiple types of biased tracers. In this brief review, we present the idea of the multi-tracer method, outline key steps in the data analysis, and show several worked examples based on the GAMA, BOSS and eBOSS galaxy surveys.
