星系之间的排列、它们潜在的物质结构和宇宙网构成了全面理解引力、物质本质和宇宙结构形成的重要组成部分。我们提供了对这些对齐过程及其观测签名的研究的艺术状态的概述，针对非专业观众。简要回顾了该领域近百年来的发展。我们还讨论了星系排列对弱引力透镜测量的影响，并讨论了在未来十年中取得理论和观测进展的途径。
The alignments between galaxies, their underlying matter structures, and the cosmic web constitute vital ingredients for a comprehensive understanding of gravity, the nature of matter, and structure formation in the Universe. We provide an overview on the state of the art in the study of these alignment processes and their observational signatures, aimed at a non-specialist audience. The development of the field over the past one hundred years is briefly reviewed. We also discuss the impact of galaxy alignments on measurements of weak gravitational lensing, and discuss avenues for making theoretical and observational progress over the coming decade.
