中等质量黑洞

太阳邻域的小型及微型暗晕和中等质量黑洞

Dark mini-halos , micro-halos and intermediate-mass black holes in the solar neighborhood

黑洞双星、中等质量黑洞和活动星系核（AGNs）都被观测到存在QPO。

QPOs have been observed in BH binaries , intermediate mass BHs and active galactic nuclei ( AGNs ) .

现在天文学家们称，他们发现的第一个确凿的证据表明，有一个难以发现的中等质量黑洞位于遥远星系的边缘上。

Now , astronomers say they have found the first conclusive evidence for one of these elusive objects at the fringe of a distant galaxy .

这个新发现的天体叫做HLX-1，是首个显示为中等质量的黑洞，介于恒星质量的黑洞和超大质量的黑洞之间。

The newly discovered object , called HLX-1 , is the first to show an intermediate weight between stellar-mass and supermassive black holes .

关于中等质量的黑洞，该发现还有一个没有解决的问题。

The find still leaves open an important question about intermediate black holes .

在宇宙中，存在着大量的重量级黑洞和轻量级黑洞，但是没有人发现过中等质量的黑洞，因此一些科学家认为中等质量的黑洞不存在。

Heavyweight and lightweight black holes abound in the universe , but nobody has detected a middleweight & and some scientists argue they don 't exist .

或者，中等质量的黑洞有可能是宇宙中最早期的恒星留下的残余物，科学家们认为当时的恒星比现在的恒星要大得多。

Or , intermediate-mass black holes could be leftovers from the very earliest stars in the universe , which scientists think were much larger than today 's versions .
