论文摘要
我们表明,地球充当暗物质低速流(DM)的高效引力收集器。当DM流速相对于地理中心约为17 km/s时,焦点出现在地球表面上。我们讨论了受地球重力影响的局部DM密度的昼夜调制。我们还谈到了对银河系和太阳系对象的类似影响。
We show that the Earth acts as a high-efficiency gravitational collector of low-velocity flow of dark matter (DM). The focal point appears on the Earth's surface, when the DM flow speed is about 17 km/s with respect to the geo-center. We discuss diurnal modulation of the local DM density influenced by the Earth's gravity. We also touch upon similar effects on galactic and solar system objects.
