论文摘要
在存在两种不同类型的DM或DM的双峰速度分布函数的情况下，我们已经通过星系分析了暗物质（DM）颗粒的捕获率。结果表明，除了我们以前的工作中考虑的情况外，基于单峰分布的假设外，更复杂的场景还可以在两个阶段发生到强烈捕获和/或退出状态的过渡。给出了描述暗物质颗粒捕获速率的曲线变化的详细说明，这是银河系重质量的增加速率，以降低DM密度的降低速率。
We have analyzed the rate of capture of dark matter (DM) particles by the galaxy in the case of the existence of two different types of DM or a bimodal velocity distribution function for DM. It is shown that, in addition to the scenario considered in our previous work which is based on the assumption of an unimodal distribution, more complex scenarios are possible in which the transition to the state of intense capture and/or exit from it can occur in two stages. A detailed description is given of the change in the curve describing the rate of capture of dark matter particles as a function of the rate of increase in the baryon mass of the galaxy for various values of the rate of decrease of the DM density.
