中国科研团队联合北京大学、中国科学院高能物理研究所等机构，在国际期刊《自然·天文学》发表研究成果，揭示了宇宙早期神秘天体"小红点"的演化机制。1研究基于近100个光谱确认的"小红点"样本，发现这些天体在宇宙极早期倾向于独居在低密度环境中。1随着宇宙演化，它们的暗物质晕质量从约100亿倍太阳质量逐步增长到约2000亿倍太阳质量，最终演化为普通星系。1
华中科技大学物理学院教授、论文通讯作者吴庆文表示，"小红点"在宇宙约20亿年后几乎完全消失。1这一研究成果为理解宇宙早期星系形成与演化过程提供了新的观测证据。
A collaborative research initiative involving Huazhong University of Science and Technology, Peking University, and the Chinese Academy of Sciences Institute of High Energy Physics has unveiled the evolutionary fate of mysterious compact objects observed in the early universe. The findings, published in Nature Astronomy, demonstrate that these celestial bodies—colloquially termed "little red dots"—undergo dramatic transformations as the cosmos ages.1
The study, based on spectroscopic analysis of nearly 100 confirmed "little red dots," traces their development across cosmic time.1 Researchers found that these objects initially reside in low-density regions of the universe, with their dark matter halos growing substantially as cosmic evolution progresses—expanding from approximately 10 billion solar masses to roughly 200 billion solar masses.1 This process eventually transforms them into ordinary galaxies indistinguishable from typical structures observed in the present-day universe. These enigmatic objects have nearly completely vanished by approximately 2 billion years after the Big Bang.1
The work was led by Wu Qingwen, a professor in the Department of Physics at Huazhong University of Science and Technology, serving as corresponding author on the publication.1
