论文摘要
我们考虑了一个包含不同质量的超光轴（ULA）的星系的两个组成暗物质光环（DMH）。 DMH被描述为基态处于其基态的Bose-Einstein冷凝物（BEC）。在平均场（MF）限制中，我们为两个DMH组件的球体对称波函数得出了整体分化方程。我们以数值为单位的ULA质量密度的径向分布，并构造了可用于区分两个组分和单成分DMH的参数。我们还讨论了一个组分DMH的BEC MF接地状态与相应黑洞的温度和熵的熵与intruh温度之间的有趣联系。
We consider a two-component dark matter halo (DMH) of a galaxy containing ultra-light axions (ULA) of different mass. The DMH is described as a Bose-Einstein condensate (BEC) in its ground state. In the mean-field (MF) limit we have derived the integro-differential equations for the spherically symmetrical wave functions of the two DMH components. We studied numerically the radial distribution of the mass density of ULA and constructed the parameters which could be used to distinguish between the two- and one-component DMH. We also discuss an interesting connection between the BEC MF ground state of a one-component DMH and Hawking temperature and entropy of a corresponding Black Hole, and Unruh temperature.
