galaxy cluster

the large galaxy is the brightest member of the centaurus galaxy cluster, some 150 million light-years away.

这个巨大的星系是距离我们1.5亿光年远的人马座星系团中最亮的成员。

this particular galaxy cluster has a mass of over one million billion suns.

这个星团的质量有超过10的15次方个太阳那么大。

the structures of two-dimensional distributions for galaxy cluster subsamples of different richness

不同富性的星系团子样本的二维分布结构

A galaxy or a star cluster consists mainly of the stars.

星系和星团主要由恒星组成。

The model with substructures can suppress the luminous central galaxy formation in cluster and can give a better luminosity function compared with the observation.

考虑到次结构一方面可以降低中心星系的亮度，同时能预言与观测很接近的光度函数形状。

recent progress of the studies of coma galaxy cluster

Coma星系团的研究进展

While studying the Coma galaxy cluster, he found that the galaxies'gravity alone was much too small to hold the cluster together.

他在研究后发座星系团的时候，发现星系本身的引力作用太小而不足以维持星系团的成型。

while researching on coma cluster, he discovered the intergalactic attraction was too weak to hold the whole galaxy cluster.

当他研究后发星系团的时候，发现星系间的引力太小无法维持住整个星系团。

well, here is an image of a particular galaxy cluster.

这里是某个星团的一张照片。

the gravitational pull of the galaxy cluster acted like a lens.

在万有引力的作用下，星系团就相当于晶状体。

comparing the calculated mass and the total mass of the light-emitting galaxies in the galaxy cluster would determine the amount of dark matter that exists in the galaxy cluster.

把计算出的质量和星系团中发光星系的总质量相比较，就能确定出星系团中存在多少暗物质。

explanation: bright lenticular galaxy m86 is near center of this cosmic view, at the heart of the virgo galaxy cluster.

说明：明亮的透镜状星系M86位于这张宇宙影像中央，在室女星系团的心脏地带。

The correlation between metallicity and stellar mass of cluster galaxies is also confirmed. It is concluded that galaxy cluster Abell 2255 is formed by the gravitational interaction after the individual galaxies are formed, which supports the hierarchical model of cluster formation.

此外还确认了团星系的金属丰度与恒星质量之间的相关性，并推断星系团Abell2255是在单个星系形成后，经过引力相互作用而形成的，这一结果支持了等级成团理论。

okay, if i take an image of a galaxy cluster,

如果我拿出一幅星团的照片，
