您要查找的是不是：
- The hierarchical formation of dark matter halos cannot be described using simple mathematical relationships. 黑暗物质晕的阶式结构无法以简单的数学关系描述。
- Because most dark matter halos end up with some angular momentum, one has to wonder why all galaxies aren't spirals. 因为多数的黑暗物质晕最终都带有角动量，我们要问：为什麽还会有星系不是螺旋星系？
- Hierarchical theories predict a proliferation of low-mass dark matter halos and, by extension, dwarf galaxies. 阶式理论预测低质量的黑暗物质晕应该很多，矮星系也是一样。
- According to their scenario, these models predict the formation of dark matter halos of a restricted type around galaxies. 根据他们的说法，这些模型预测在星系周围会形成一类特殊的暗物质晕。
- Either these dark matter halos do not exist or they are present but have eluded detection because stars do not form within them. 所以黑暗物质晕要不是根本就不存在，就是存在但侦测不到，因为星球不会在里头形成。
- In the current paradigm of galaxy formation, disk galaxies are assumed to form by the cooling and condensation of baryons within dark matter halos. 目前的星系形成理论认为，盘状星系由暗晕中的重子物质冷却并坍缩而成。
- Such a dark matter halo might explain the anomalies seen in the orbits of the Pioneer, Galileo, Cassini, Rosetta and NEAR mission spacecraft, he adds. 这些暗物质或许可以解释先锋号、伽利略号、卡西尼号、罗塞塔号以及近地小行星会合号任务太空船在轨道上的一些异常现象。
- The end point of the collapse and relaxation of a protogalaxy is a dark matter halo, inside of which the baryonic gas is in hydrostatic equilibrium at a temperature of typically a few million degrees. 原星系塌缩与松弛的最终点就是黑暗物质晕，里面有处于流体静力平衡的重子气体，一般温度约数百万度。
- dark matter halos 暗物质晕
- But Dr Treu found that the dark matter extended further than the visible matter, forming a halo around it. 但他还发现暗物质的分布范围远比可见物质来的广，并参与形成了其上的光环。
- Dark Matter in The Universe -- Extended Ed. 宇宙暗物质扩充版。
- WHAT KIND OF particle could dark matter be made of? 暗物质可能是由哪一种粒子组成的呢?
- The problem is that dark matter is invisible. 问题在于暗物质看不见。
- One kind of hot dark matter is known, the neutrino. 已知的一类热暗物质是微中子。
- NASA's Hubble Space Telescope has uncovered a strong new line of evidence that galaxies are embedded in halos of dark matter. 哈勃已经发现了（矮）星系深植在暗物质晕中的一系列新的强力证据。
- Second, whereas the baryons and CDM were initially well mixed, the baryons today form dense knots (the galaxies) inside gargantuan halos of dark matter. 第二，尽管起初重子与CDM均匀地混在一起，今天的重子，在庞大的黑暗物质晕中形成了浓密的集团（即星系）。
- In the violence of the encounter, streamers of galactic material are pulled out away from the parent galaxies and the halos of dark matter that surround them. 在这一剧烈的相撞过程中，星系物质被抛离其母星系以及围绕它们的暗物质。
- Hence we infer that there is dark matter in the Universe. 因此我们推断出宇宙中存在暗物质。
- THE MASS FUNCTION OF DARK MATTER HALOES IN A COSMOLOGICAL MODEL WITH A RUNNING PRIMORDIAL POWER SPECTRUM 原初连续功率谱宇宙模型下暗物质晕的质量函数
- Firstly, the understanding of baryon dark matter is reviewed, and the dark celestial body in our galaxy is called massive astrophysical compact halo object (MACHO). 简要回顾了对重子暗物质的认识过程，其中广泛分布于星系之中的暗天体被称为晕族大质量致密天体(MACHO)。
