查询词典 galaxies

Dwarf galaxies such as the Small Magellanic Cloud, with significantly fewer stars compared to our own galaxy, are considered to be the primitive building blocks of larger galaxies.

如小麦哲伦云这样的矮星系——与我们的银河系相比恒星数少得多——被认为是巨星系的形成基础。

After a cross-identification between the photometric data obtained from the BATC and SDSS, a catalog containing 1553 galaxies down to r'=20.0 mag is achieved, which includes 121 spectroscopically confirmed member galaxies.

通过BATC和SDSS星表的交叉证认，得到了一个极限星等r'=20.0mag，包含1553个星系的星表，其中有121个通过分光红移证认的成员星系。

The spaces between galaxies that are part of clusters, however, are filled with hot, rarified gas that does not get incorporated into the individual galaxies very efficiently.

然而，在星系团内部，星系与星系之间的太空中充满了炽热、稀薄的气体，无法高效地融入到各星系中去。

At least some elliptical galaxies, as well as the bulges and halos of spiral galaxies, may have arisen from such collisions.

至少螺旋星系的核球与晕，以及某些椭圆星系，可能是由此种碰撞产生的。

Major advances have been made in the last a few years, including the discovery of fading X-ray, optical and radio afterglows of GRBs, the identification of host galaxies at cosmological distances, and evidence showing that many GRBs are associated with star-forming regions of the host galaxies and possibly a peculiar type of supernova.

过去几年里γ暴的研究取得了重大突破，包括发现了变暗的X射线、光学和射电余辉，探测到位于宇宙学距离的寄主星系，发现γ暴与恒星形成区成协、甚至可能与超新星关联的证据等等。

The formation and evolution of disks are important for the formation and evolution of spiral galaxies, for disks are important components of the galaxies and the most baryons are in disks.

中文摘要：在旋涡星系形成和演化的过程中，星系盘的形成和演化是关键，因为盘是星系的主要成份，大部分的重子物质都包含在星系的盘中。

This Confederation works with the planetary spheres of seven of your galaxies, if you will, and is responsible for the callings of the densities of these galaxies.

这个星际联邦的工作范围为你们的七个星云系，如果你愿意这样称呼，并且负责这些星云系各个密度的呼求。

The new technique reduced the distance ladder to three "rungs":(1) The distance to galaxy NGC4258 is measured using straightforward geometry and Kepler's laws;(2)Cepheids in six more distant galaxies are used to calibrate the luminosity of Type Ia supernovae;(3) The Hubble constant is measured by observing a brighter milepost marker, Type Ia supernovae, in more distant galaxies hundreds of millions of light-years away, embedded in the expanding universe.

这种新技巧简化了距离跳跃为三个&阶梯&：1、星系NGC 4258的距离采用开普勒定律和简单直接的几何方法精确测量；2、在6个更远的星系中的造父变星用来校准Ia超新星的光度；3、深嵌于数亿光年外的膨胀宇宙中的星系中的Ia超新星——一种遥远而明亮的量天尺，被用于精确测定哈勃常数。

By studying galaxies at different epochs, astronomers can see how galaxies change over time.

通过研究星系的不同时期，天文学家能够观测星系整个的演化过程。

Our results reconcile and quantify the earlier contradictory findings in the frame that the effect of bar on starburst is associated with the relative far-infrared luminosity and it is detectable only in galaxies with L〓/L〓 larger than 1/3, suggesting that bars translate their host galaxies into the relative IR-luminous group.

我们发现棒的确增强了早型星系中的星暴，但是在晚型星系中没有影响，同时棒的作用是和星系的相对远红外光度相联系的，对不同的L〓/L〓范围，棒的作用会从减弱，到无关，再到增强星暴。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
