【摘要】:暗物質(zhì)是宇宙的主要物質(zhì)成分,但其本質(zhì)是什么仍然是現(xiàn)代科學(xué)亟待解決的一個(gè)重大問(wèn)題。粒子物理學(xué)提供了多種暗物質(zhì)粒子的候選者,不同的暗物質(zhì)模型在宇宙小尺度結(jié)構(gòu)方面有迥然不同的預(yù)言,所以原則上人們可以通過(guò)天文觀測(cè)來(lái)限制暗物質(zhì)粒子的屬性。文章首先綜述了暗物質(zhì)粒子屬性對(duì)宇宙結(jié)構(gòu)形成的影響,然后闡述目前流行的冷暗物質(zhì)宇宙學(xué)模型面臨的一些困難,最后討論用天文學(xué)區(qū)分冷、溫暗物質(zhì)模型的天文學(xué)方面研究進(jìn)展情況。
[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.
