静止参考架（rest frame）光学波段下“小红点”的延展成分

韦布空间望远镜（JWST）的观测揭示了“小红点”在静止参考架光学波段下的延展宿主星系。这些发现为理解早期黑洞（black hole）如何在最初的十亿年内与其宿主星系共同生长提供了线索。

Nature Astronomy, Published online: 24 August 2026; doi:10.1038/s41550-026-02945-z JWST observations reveal extended host galaxies around little red dots at rest-frame optical wavelengths, shedding light on how early black holes grew together with their host galaxies within the first billion years.
