詹姆斯·韦伯太空望远镜观测到的神秘"小红点"可能是早期宇宙中快速增长的黑洞。由马克斯·普朗克天体物理研究所的Sunmyon Chon领导的研究团队利用日本国家天文台的ATERUI III超级计算机进行高分辨率宇宙学模拟，得出了这一发现1。研究表明，这些被称为小红点（LRDs）的天体可能是快速增长的黑洞，其增长速度比现代宇宙中的黑洞快数十倍1。
早期宇宙中超大质量黑洞的形成是天文学的长期谜团。一些超大质量黑洞已含有太阳质量的数百万倍甚至数十亿倍，但却在大爆炸后不到6亿年内就已出现1。研究表明，极端紫外辐射可能有助于形成异常巨大的黑洞种子，而周围稠密气体使其能够以极快的速度增长1。如果这一结论正确，将解释超大质量黑洞如何在如此短的宇宙时间尺度内形成的谜团1。该研究论文已发表在《Nature》2026年657卷第8132期1。
A new simulation study conducted on Japan's ATERUI III supercomputer suggests that the enigmatic small red dots observed by the James Webb Space Telescope could represent rapidly growing black holes in the early universe.1 Led by Sunmyon Chon at the Max Planck Institute for Astrophysics, the research employed high-resolution cosmological simulations to explore how these objects might have formed.1
According to the findings, black holes in the early universe could have grown at rates tens of times faster than their modern counterparts, potentially driven by extreme ultraviolet radiation and dense surrounding gas that enabled the formation of unusually massive black hole seeds.1 This mechanism may resolve a long-standing puzzle: some supermassive black holes contain millions or even billions of solar masses, yet they appeared less than 600 million years after the Big Bang.1 The JWST has detected numerous tiny, extremely red objects—designated as little red dots (LRDs)—which the simulations suggest could explain this rapid early growth.1 The research was published in Nature, volume 657, issue 8132, page 621.1
