类星体

This class of objects is thought to have relatively small black hole mass and to accrete at a high Eddington ratio.

这类类星体通常被认为具有相对小的黑洞质量以及高Eddington比率的吸积率。

The accretion onto the black hole is the source of the quasar's energy.

黑洞吸积是类星体的能量来源。

The system has a nuclear region of quasar-like luminosity, but shows no direct evidence for an active nucleus.

该系统有一个类星体般光度的核心区域，但是没有直接证据表明有一个活动的核。

Now, in a posting on the Galaxy Zoo blog, Dr Keel and Dr Lintott suggest that the galaxy right next door to the voorwerp used to be a quasar (a very bright active galactic nucleus) that has since eaten up all its fuel.

现在，在星系动物园博客上的一个帖子中，Keel 博士和 Lintott 博士认为在"物体"旁边的星系曾经是个类星体（一种很明亮的活跃星系核），但现在已经把它的燃料给消耗光了。

Seeing that the regression equations with high correlation coefficient among redshifts, apparent magnitude and D have been established, it may be true that the redshift of these quasars is ma...

由于红移，视星等及D之间存在着相关系数较高的回归关系，所以，这种类星体的红移可能主要是宇宙学的。

Based on our reduction of the ASCA observational data and fittings of the low and medium energy X-ray spectra, we combine the ASCA and BeppoSAX observed PG QSOs to form a sample for statistics of the spectral features on the X-ray spectra.

从处理ASCA观测数据和分析X射线谱出发，将有ASCA和BeppoSAX观测结果的PG类星体构成一个样本，对它们的中、低能X射线谱上的观测特征进行统计。

Dad explained light-years and black holes and quasars24 and told us about the special qualities of Betelgeuse, Rigel, and Venus.

父亲向我们解释了光年、黑洞和类星体，还告诉我们猎户座α、猎户座β和金星的特别之处。

In the early universe, collisions—and hence quasars—occurred more often because galaxies were packed much more closely together.

在早期宇宙中，星系碰撞以及因此而形成类星体的情况发生得更加频繁，因为当时星系之间的距离要接近得多。

The results show that the emission line region is at least several tens light-days away from the central black hole!

认为类星体发射线辐射区应在离中心黑洞几十个光日处，仅是一种理论解释。

Bao made another mistake. He incorrectly thinks that the emission line region is the same as accretion disk!

我们确实应当化更多的时间去了解现代对类星体的观测结果，了解现有的理论。

Since historical times,England ,where the early inhabitants were Celts, has been conquered three times .

从有历史以来，英国，在此地早期居住的是凯尔特人，已经被征服了三次。
