暗物质粒子属性和宇宙结构形成

Dark matter and the formation of cosmic structures

  • 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 dominating component of our universe; however, the nature of dark matter remains unknown. There exist many candidate constituents from particle physics which give very different predictions of the formation of small scale cosmic structures, so in principle we can distinguish the nature of dark matter through astronomical observations. In this article we first review the impact of different dark matter modes on cosmic structure formation, and then describe some apparent problems in the current standard cold dark matter model. Finally, we discuss recent progress in using astronomy to distinguish between cold and warm dark matter .
