论文摘要
宇宙空隙构成了有希望的宇宙实验室。但是，必须对影响观测测量的所有红移空间效应进行完整描述，以获得无偏见的宇宙学约束。简而言之，我们对这些效果进行了描述，并为基于空隙尺寸函数和void-galaxy互相关函数设计可靠的宇宙学测试的理论基础。我们表明，现代光谱调查提供了高信噪比，以检测和研究它们。
Cosmic voids constitute promising cosmological laboratories. However, a full description of all the redshift-space effects that affect observational measurements is mandatory in order to obtain unbiased cosmological constraints. We make a description in a nutshell of these effects and lay the theoretical foundations for designing reliable cosmological tests based on the void size function and the void-galaxy cross-correlation function. We show that modern spectroscopic surveys offer a high signal-to-noise ratio to detect and study them.
