暗物质粒子属性和宇宙结构形成
发布时间：2018-08-02 18:37
【摘要】：暗物质是宇宙的主要物质成分,但其本质是什么仍然是现代科学亟待解决的一个重大问题。粒子物理学提供了多种暗物质粒子的候选者,不同的暗物质模型在宇宙小尺度结构方面有迥然不同的预言,所以原则上人们可以通过天文观测来限制暗物质粒子的属性。文章首先综述了暗物质粒子属性对宇宙结构形成的影响,然后阐述目前流行的冷暗物质宇宙学模型面临的一些困难,最后讨论用天文学区分冷、温暗物质模型的天文学方面研究进展情况。
[Abstract]:Dark matter is the main material component of the universe, but its essence is still a major problem to be solved in modern science. Particle physics provides candidates for a variety of dark matter particles. Different models of dark matter have very different predictions about the structure of the universe on a small scale, so in principle people can limit the properties of dark matter particles by astronomical observation. This paper first summarizes the influence of the properties of dark matter particles on the formation of the cosmic structure, then expounds some difficulties faced by the prevailing cold dark matter cosmological models, and finally discusses the use of astronomy to distinguish cold matter. Advances in astronomical aspects of thermo-dark matter models.
