"This is basically a new method to render dark galaxies visible," she said, adding that her technique should be able to detect dim dwarf galaxies as small as a thousandth the mass of the Milky Way.
“这在根本上是一个使暗星系可见的全新方法,”她说道,通过她的方法将使得小到只有银河系千分之一质量的暗矮星系能被观测到。
Both groups searched for the gamma-ray glow from dark matter in dwarf galaxies orbiting the Milky Way.
两组研究了环绕银河系的矮星系中的暗物质放射的伽马射线。
The dwarf galaxies may have even a higher amount of dark matter than spiral galaxies.
矮星系也许比螺旋状星系含有更多的暗物质。
The problem is dwarf galaxies are not as dense as the cold dark matter model says they should be.
问题在于矮星系并没有它们本应具有的冷暗物质的密度。
The problem is that dwarf galaxies are not as dense as the cold dark matter model says they should be.
问题在于矮星系并没有它们本应具有的冷暗物质的密度。
So dwarf galaxies would presumably exhibit the cusp of dark-matter particles in their centers that spirals lack.
所以矮星系在其中心可能存在着暗物质的尖点而螺旋星系不太可能。
That makes it a lot harder to gauge the density of dark matter as you get closer to the center of the dwarf.
这种无序使得在矮星系中心测量暗物质的密度非常难。
