摘要
宇宙中的巨型光弧是近两年来发现的一种新颖的天象。本文简述了已有的四个观测事例,给出了可能的产生机制,特别就引力透镜的成因进行了仔细的讨论。
Giant luminous arcs, the hitherto unknown types of structures in the Universe, were discovered over past two years. In this review paper, the four cases of the arcs known so far are listed and the various conjectures, especially the gravitational lensing model, about these unusual features are discussed.
