巨型黑洞的演化

Astronomers are concluding that monstrous black holes weren't simply born big but instead grew on a measured diet of gas and stars controlled by their host galaxies in the early formative years of the universe. These results, gleaned from a NASA Hubble Space Telescope census of more than 30 galaxies, are painting a broad picture of a galaxy's evolution and its long and intimate relationship with its central giant black hole. Though much more analysis remains, an initial look at Hubble evidence favors the idea that titanic black holes did not precede a galaxy's birth but instead co-evolved with the galaxy by trapping a surprisingly exact percentage of the mass of the central hub of stars and gas in a galaxy.

天文学家得出结论，超级黑洞并非简单的生成，而是靠吞噬气体和恒星而缓慢变大，它们在宇宙早期形成，受寄主星系的控制。上述结论是在NASA的哈勃太空望远镜调查了30多个星系后得出的，该结论描绘出了清晰的星系演化过程，以及星系与其中心巨大的黑洞漫长而密切的关系。虽然需进一步的分析，但是哈勃给出的证据仍然支持下述结论：巨大的黑洞并非先于星系而形成，而是以相当精确的质量比例在星系中心捕获气体和恒星，进而与星系共同演化而来。d
