The paper consistently presents the history and methodology of observational searches for cosmic strings of various nature. Cosmic strings are one-dimensional extended objects predicted by modern cosmology, which, however, have not yet been detected with a high degree of confidence. The presence of cosmic strings changes the global geometry of the Universe and could serve as a unique proof of higher-dimensional theories. The properties and features of these cosmological objects from the point of view of observational astronomy are discussed. The presentation is preceded by a brief mathematical theory of cosmic strings.

太空织物皱纹:观测搜索宇宙中奇异结构的历史

该论文一致地介绍了各种性质的宇宙弦观测搜索的历史和方法。宇宙弦是现代宇宙学预测的一维扩展物体,但尚未被高度可信地探测到。宇宙弦的存在改变了宇宙的整体几何形状,并可以作为高维理论的独特证明。从观测天文学的角度讨论了这些宇宙物体的性质和特征。演讲之前先简要介绍宇宙弦的数学理论。
