对最大宇宙旋转结构的研究，其实也是对星系内在排列的研究。可以说，这一发现不仅深化 了人们对星系自旋的理解，还将影响未来宇宙学模拟和巡天项目，如欧空局的欧几里得任务 和鲁宾天文台的弱透镜巡天。值得一提的是，这一成果能诞生，得益于全球多台望远镜数据 的结合和国际合作，这也体现了大型团队协作在现代天文学研究中的重要性。 进一步研究中，通过分析丝状体两侧星系的运动，团队发现其一侧星系远离观测者（红移），另一侧靠 近观测者（蓝移）。即主轴两侧的星系呈相反方向运动，这暗示整体结构存在旋转。动力学模型显示， 其旋转速度达110公里/秒。 团队将这一结构比作"公园的茶杯游乐设施"。每个星系都如同旋转的茶杯，而整个丝状体平台也在旋 转，这种双重运动为理解星系获取角动量提供了罕见机会，同时揭示了物质如何通过丝状体被输送到星 系中，并在宇宙网中传递。（记者张梦然） 总编辑圈点 英国牛津大学领导的国际团队确认了迄今观测到的最大宇宙旋转结构——一个距离地球约1.4亿光 年、"如刀刃般"嵌入巨大旋转宇宙丝状体中的星系链。它被称为"宇宙流动的化石记录"，为研究早期宇 宙星系形成提供了全新视角。该发现12月4日发表在《皇家天文学会月报》。 ...

Core Insights - The research team led by Professor Wang Huiyuan from the University of Science and Technology of China has discovered strong clustering of diffuse dwarf galaxies, confirming the phenomenon of "dark matter halo clustering bias" in the universe, which provides important clues for understanding the nature of dark matter and the co-evolution of cosmic large-scale structures and galaxies [1][2] Group 1: Dark Matter and Galaxy Formation - Dark matter is an invisible and non-luminous substance that shapes the structure of the universe through gravity, dominating the formation and evolution of galaxies [1] - The distribution of dark matter halos is not uniform but exhibits a "clustering" pattern, which is crucial for understanding the large-scale structure of the universe and galaxy formation [1] - The research team found that diffuse dwarf galaxies prefer to cluster together, while compact dwarf galaxies tend to be more isolated, contradicting previous findings based on massive galaxy samples [1] Group 2: Alternative Models and Theoretical Implications - The standard cold dark matter model, which is the mainstream theoretical framework for explaining the formation of large-scale structures in the universe, fails to effectively explain the new findings [2] - An alternative model considering self-interacting dark matter (SIDM) was proposed, which can explain the correlation between dark halo "age" and galaxy density, presenting unique theoretical advantages [2] - This research challenges existing galaxy formation models and provides new insights into the nature of dark matter, moving closer to unveiling its mysteries [2]
