美国航天局的IXPE飞行任务确认 黑洞喷气机的X光 来自高速电子 与光子碰撞 解决了60年的谜团 NASA's IXPE mission confirmed that X-rays in a black hole jet come from high-speed electrons colliding with photons, solving a 60-year mystery.

美国航天局的IXPE飞行任务通过在3C84星系内一个超大型黑洞喷气式喷射机中查明X射线来源,解决了一个长达数十年之久的谜团。 NASA's IXPE mission has solved a decades-old mystery by identifying the source of X-rays in a supermassive black hole’s jet within the galaxy 3C 84. 经过600小时的观察,IXPE检测到4%的X射线两极分化,证实X射线是Compton反向散射的结果——低能光子通过与喷气机高速电子碰撞而获得能量。 After 600 hours of observation, IXPE detected a 4% X-ray polarization, confirming that the X-rays result from inverse Compton scattering—where low-energy photons gain energy by colliding with high-speed electrons in the jet. Chandra、Nustar和Swift的数据支持这一结论,排除了外部来源,并验证了同步器自Compton模型。 Data from Chandra, NuSTAR, and Swift supported this conclusion, ruling out external sources and validating the synchrotron self-Compton model. 研究结果发表于2025年11月11日, 加深了对黑洞喷射物理学的认识, The findings, published November 11, 2025, advance understanding of black hole jet physics and highlight IXPE’s role in probing extreme cosmic environments.
