轴子暗物质的情况
The Case for Axion Dark Matter
摘要：
暗物质轴子形成再热的玻色-爱因斯坦凝聚体。这提供了一个机会，从观测的角度来区分轴子和其他形式的暗物质。我表明，如果暗物质是轴子，潮汐扭矩理论预测的孤立盘星系，如银河系的晕的相空间分布的特定结构。这种相空间结构正是焦散环模型的相空间结构，而焦散环模型的相空间结构在早期已经得到了观测的支持。其他的暗物质候选者预测了星系晕的不同相空间结构。
英文摘要：
Dark matter axions form a rethermalizing Bose-Einstein condensate. This provides an opportunity to distinguish axions from other forms of dark matter on observational grounds. I show that if the dark matter is axions, tidal torque theory predicts a specific structure for the phase space distribution of the halos of isolated disk galaxies, such as the Milky Way. This phase space structure is precisely that of the caustic ring model, for which observational support had been found earlier. The other dark matter candidates predict a different phase space structure for galactic halos.
