韦布望远镜发现早期宇宙超大质量黑洞

Core Insights - The European Space Agency reported the discovery of an actively growing supermassive black hole in a galaxy just 570 million years after the Big Bang, which could reveal key mechanisms behind the origins of black holes and galaxies [1] Group 1: Discovery Details - Researchers utilized the James Webb Space Telescope's near-infrared spectrograph to detect faint light from the distant galaxy CANUCS-LRD-z8.6 [1] - Analysis of the galaxy's spectral features indicates the presence of an accreting black hole that is growing at a rate exceeding expectations [1] Group 2: Characteristics of the Galaxy - The galaxy is described as very dense and has not yet produced a significant amount of heavy elements, confirming its status as an early-stage galaxy [1] - The gas within the galaxy shows signs of strong ionization from high-energy radiation and rapid rotation around a central source, which are key characteristics of an accreting supermassive black hole [1] Group 3: Implications for Black Hole Growth - Notably, the mass of the black hole in this galaxy is disproportionately large compared to the stellar mass, suggesting that black holes may grow faster than their host galaxies in the early universe [1] - This observation challenges the previously established correlation between the mass of supermassive black holes and their host galaxies, indicating that black holes could form and accelerate growth even in relatively small galaxies during the early universe [1]
