国际研究团队在遥远星系中实现了一项重要发现。由马克斯·普朗克天体物理研究所领导的研究团队在距离地球超过125亿光年的星系J0148-4214中发现了三个活跃进食的超大质量黑洞1，这是宇宙极早期的罕见现象。该星系的红移值为5.02，意味着观测的是大爆炸后约12亿年时期的宇宙1。
这三个黑洞的质量分别约为太阳的80万倍、600万倍和8000万倍1。其中两个中心黑洞相距仅620光年，预计将在未来数亿年内合并1，而第三个黑洞距离星系中心约5500光年1。该星系的恒星总质量约为太阳的13亿倍1。
研究团队利用詹姆斯·韦伯太空望远镜的近红外光谱仪积分场谱学模式进行了观测1。值得注意的是，次大黑洞的吸积速率超过了爱丁顿极限——这是基本黑洞增长模型预测的最大值1。这一发现可能揭示了早期宇宙中黑洞快速增长的机制，是首次在遥远宇宙的单个星系中获得三个活跃黑洞的直接证据1。
An international research team led by the Max Planck Institute for Astrophysics has identified three actively feeding supermassive black holes in galaxy J0148-4214, located more than 12.5 billion light-years from Earth 1. This discovery represents a rare phenomenon in the early universe, observed as it existed approximately 1.2 billion years after the Big Bang 1. The finding provides unprecedented evidence of multiple active black holes within a single distant galaxy 1.
The three black holes possess vastly different masses, estimated at approximately 800,000, 6 million, and 80 million times the mass of the Sun 1. Two of the central black holes are separated by just 620 light-years and are expected to merge within hundreds of millions of years 1. The third black hole is located approximately 5,500 light-years from the galaxy's center 1. The most massive black hole dominates the system, while the second-largest black hole exhibits an accretion rate that exceeds the Eddington limit, the theoretical maximum predicted by fundamental black hole growth models, potentially revealing mechanisms by which black holes rapidly grew in the early universe 1. The host galaxy itself contains approximately 1.3 billion times the Sun's mass in stars 1.
Researchers utilized the James Webb Space Telescope's Near Infrared Spectrograph Integral Field Spectroscopy mode (NIRSpec-IFS) to conduct detailed observations of the system 1. This analysis marks the first time that evidence of three active black holes has been confirmed within a single galaxy in the distant universe 1.
