宇宙的压抑：生活，社会学和虚空的身份
The Cosmically Depressed: Life, Sociology and Identity of Voids
摘要：
我们回顾并讨论了宇宙空洞的各个方面，这些方面构成了我们的虚空星系调查的背景（参见Stanonik等人的随附论文）。在概述了空洞形成和演化的一般特征之后，我们描述了环境对它们的发展和结构的影响以及宇宙空洞人口的特征层次结构。为了能够研究由此产生的脆弱的空洞子结构和星系填充内部的空洞，我们随后开始描述我们的参数自由镶嵌为基础的分水岭空洞寻找技术。它使我们能够在星系红移巡天中追踪空洞的轮廓、形状和大小。这项技术的应用使我们能够在宇宙星系分布的最深槽中找到星系，并形成了我们的虚空星系计划的基础。
英文摘要：
We review and discuss aspects of Cosmic Voids that form the background for our Void Galaxy Survey (see accompanying paper by Stanonik et al.). Following a sketch of the general characteristics of void formation and evolution, we describe the influence of the environment on their development and structure and the characteristic hierarchical buildup of the cosmic void population. In order to be able to study the resulting tenuous void substructure and the galaxies populating the interior of voids, we subsequently set out to describe our parameter free tessellation-based watershed void finding technique. It allows us to trace the outline, shape and size of voids in galaxy redshift surveys. The application of this technique enables us to find galaxies in the deepest troughs of the cosmic galaxy distribution, and has formed the basis of our void galaxy program.
