Cobe的设计只是为了观测最大的结构,但天文学家们也希望看到更小的热点,即星系团和超星系团等局部天体的种子。
Cobe is designed to see just the biggest structures, but astronomers would like to see much smaller hot spots as well, the seeds of local objects like clusters and superclusters of galaxies.
典型的超星系团本应该含有成串的小星系团。
Typical superclusters have many smaller clusters connected by these threads.
在其内部,这条“长城”包含几个有趣的超星系团。
Within it, the Wall contains several interesting superclusters.
典型的超星系团本应该含有成串的小星系团。
Typical super clusters have many smaller clusters connected by these threads.
曾经有人以为这是造成银河组成超星系团的原因,不过后来这种想法被抛弃。
This was once thought to be what caused galaxies to form in supercluster complexes, although this idea has since been abandoned.
物质在它们的重力作用下聚集成行星、恒星、星系、星系团和超星系团。
Matter clumps under its own gravity into planets, stars, galaxies, clusters, and superclusters.
然而,这些模型在解释sci 126那样的尺寸、形态和分布情况的超星系团时却不合适。
However, they fall short in creating superclusters with the size, morphology and distribution of SCl 126.
为了达到这些目的,作者需要继续研究斯隆长城和其它超星系团的形态,并把它们的特征作以比较。
To help achieve this, the authors intend to continue mapping the morphology of the Sloan Great Wall as well as other superclusters to compare their features.
通常来说,宇宙微波背景辐射粒子先发生了蓝移(它们的峰向光谱的蓝端移动),但当它进入超星系团之后又发生了红移。这两个效果相互抵消。
Normally a CMB photon is first blueshifted (its peak shifts towards the blue end of the spectrum) when it enters the supercluster and then redshifted as it leaves, so that the two effects cancel.
作者提到,总的来说,模型对于结构类似SCI 111的超星系团和我们已经在宇宙中观测到的大部分其它大部分超星系团的适用性很好。
The authors note that models have generally done a good job of being able to account for structures similar to SCl 111 and most other superclusters we have observed in the universe.
