Also, VSOP cannot frequently change observing object, hence it cannot supply more observations to many quasars, which are required for geodesy and geodynamics.

VSOP还不适合于频繁改变观测对象，所以无法提供针对多个射电源的观测量，而这正是大地测量和地球动力学所需要的。

the supermassive black holes that are still active, however, do not exhibit the same behavioral patterns as the distant quasars.

但是，目前仍活跃的超大质量黑洞，其行为模式与遥远的类星体并不相同。

The notion that obscured quasars are the byproduct of galaxy mergers has been around for quite a while, adds astronomer Christopher Reynolds of the University of Maryland, College Park.

马里兰大学的Christopher Reynolds补充说，一直流行的观念是，混沌的类星体是星系融合的副产品。

So, we can use quasars probing the early Universe and large& scale structure of the universe.

因此，我们可以用类星体来探测早期宇宙和宇宙大尺度结构。

A number of quasars with redshift Z> 4 have been discovered in recent years, which provide important constraints to theoretical models for the large scale structure evolution of the universe and the formation of galaxies at early time.

近年来发现了一批Z>4的类星体，这些高红移类星体使人们对早期宇宙中的大尺度结构演化和星系形成的理论模型提出了新的观点。

Finally, we discuss the application of MR relation in astrophysics, which is focused on black hole binaries and radio dichotomy of quasars.

最后，我们介绍了MR关系在天体物理学上的运用。MR关系在天体物理的应用主要是两个方面，一个是在黑洞双星上的应用，另一个是关于类星体射电二分的应用。

a decade ago, webb used observations from the keck telescope in hawaii to analyse the light from distant galaxies called quasars.

十年前，韦伯使用了夏威夷的凯克望远镜（Kecktelescope）观测和分析了从遥远的、称为类星体的星系所发射出来的光线。

The findings provide" powerful insights into how quasars form and evolve," says astronomer Amy Barger of the University of Wisconsin, Madison.

威斯康星大学麦迪逊分校的天文学家艾米·巴杰说，这些发现在类星体的形成和演化方面提供了深刻的认识。
