一 | 中新网北京8月24日电 (记者 孙自法)宇宙中的小红点究竟是怎样的存在？北京时间8月24日夜间，施普林格·自然旗下专业学术期刊《自然-天文学》在线发表中国学者领衔完成的一篇研究论文认为，小红点可能位于总质量约为太阳10亿倍的小型致密宿主星系中。 (ECNS) -- Ning Boyu, a principal engineer at China's tech giant Huawei, recently announced on social media that he has left the company and will pursue postdoctoral research at KTH Royal Institute of Technology in Sweden. Explaining his decision, Ning said that during his time at Huawei, he noticed a gap between industry needs and academic research. After discussing these issues with university professors and students, he realized that he particularly enjoyed engaging with the academic community, according to Jiupai News, a media outlet in Hubei province. Ning said he has received a Marie Curie postdoctoral fellowship and will conduct research at KTH Royal Institute of Technology. He plans to return to China after completing the program. Widely known as a member of Huawei’s Top Minds program, the 30-year-old described his three years at the company as a valuable experience that sharpened his skills and allowed him to forge lasting friendships with colleagues. Asked about the “Top Mind” label, Ning admitted that after joining Huawei, he realized he was not necessarily the most outstanding employee in terms of either technical ability or intellect. This led him to question whether he truly deserved the title. In his own assessment, his strengths include a passion for research, a willingness to delve deeply into problems, a habit of getting to the root of issues, and an ability to simplify complex matters. However, he also acknowledged several weaknesses, including an average memory, difficulty multitasking, a tendency to have many scattered ideas, and a mind that often jumps from one thought to another in both work and daily life. Recently, Ning helped a relative sell freshly harvested corn. He described it as a completely new experience that gave him a deeper appreciation of the challenges faced by people from all walks of life.

这一重要天文发现，为宇宙大爆炸后最初十亿年间小红点等神秘天体的形成提供了新见解。

该论文介绍，宇宙小红点是近年来天文学界关注到的遥远的微小红色天体，其中心可能存在超大质量黑洞。
二 | 不过，这些小红点的本质和它们光的来源尚不明确。过去的研究在紫外波段发现部分小红点周围存在微弱的延展成分，可能表明存在宿主星系的特征。
三 | 不过，在光学波段(人眼可见光波段)还鲜有证据可以探测到这些结构成分，而光学波段能更明确地揭示恒星质量。 在本项研究中，论文共同通讯作者、武汉大学教授丁旭恒和湖南师范大学特聘教授杨里岚与同事及国际合作者一起，结合詹姆斯·韦布空间望远镜217个小红点的图像，揭示出在单张影像中无法明确检测到的微弱光学发射(延伸至中心天体之外的光)。 研究团队通过数据建模表明，这些光学发射可能来自正在形成恒星的宿主星系，这些星系平均半径仅210秒差距(约685光年)，其紧凑程度约为宇宙历史中相近时期其他相似质量恒星形成星系的2.5倍。 研究团队认为，这些天文学研究发现表明，宇宙小红点并不是孤立的点光源，其周围很可能还存在一个紧凑的宿主星系，这为揭示小红点究竟是什么、又是如何形成的提供了重要线索。
四 | 他们也提醒说，本项研究揭示的是小红点这一群体的平均特征。由于其宿主星系发出的光十分微弱，目前在大多数单个小红点中还难以直接探测到。因此，后续研究需要利用更多波段、更深的观测以及更大的样本进一步验证这一发现，并结合光谱信息了解这些宿主星系的性质，进而探索早期宇宙中星系与中心黑洞的共同演化关系。(完) 【编辑:万纪玮】。
