寻找空间黑洞--X射线观测的关键作用

Searching for Black Holes in Space - the key role of X-ray observations

Ken Pounds

摘要:

虽然广义相对论提供了黑洞的物理基础,但它们存在的证据必须等到太空时代,当时X射线观测首次将天文学家的注意力引向不寻常的双星天鹅座X-1和A0620-00。随后,一些主要位于银河系高纬度的微弱的Ariel 5和Uhuru源被发现靠近明亮的Seyfert星系,这表明活动星系核的核活动也可能是由黑洞的强引力吸积驱动的。后来用EXOSAT探测到快速X射线变化,证实活动星系核中的吸积物体几乎肯定是一个超大质量黑洞。

英文摘要:

Although General Relativity had provided the physical basis of black holes, evidence for their existence had to await the Space Era when X-ray observations first directed the attention of astronomers to the unusual binary stars Cygnus X-1 and A0620-00. Subsequently, a number of faint Ariel 5 and Uhuru sources, mainly at high Galactic latitude, were found to lie close to bright Seyfert galaxies,suggesting the nuclear activity in AGN might also be driven by accretion in the strong gravity of a black hole. Detection of rapid X-ray variability with EXOSAT later confirmed that the accreting object in AGN was almost certainly a supermassive black hole.
