Via Lactea INCITE模拟：高分辨率的银河系暗物质子结构
The Via Lactea INCITE Simulation: Galactic Dark Matter Substructure at High Resolution
摘要：
这是对宇宙结构形成的冷暗物质范式的一个明确而独特的预测，即星系是分层形成的，并嵌入大量的、扩展的暗晕中，这些暗晕充满了自约束的子结构或“subhalos”。围绕其宿主的暗晕的数量和空间分布提供了关于星系组装过程和暗物质性质的独特信息和线索。在这里，我们提出的结果，从通过Lactea INCITE模拟，一个十亿粒子，一百万CPU小时的模拟银河系暗物质晕及其子结构人口的形成和演化。
英文摘要：
It is a clear unique prediction of the cold dark matter paradigm of cosmological structure formation that galaxies form hierarchically and are embedded in massive, extended dark halos teeming with self-bound substructure or "subhalos". The amount and spatial distribution of subhalos around their host provide unique information and clues on the galaxy assembly process and the nature of the dark matter. Here we present results from the Via Lactea INCITE simulation, a one billion particle, one million cpu-hour simulation of the formation and evolution of a Galactic dark matter halo and its substructure population.
