宇宙中暗物质观测证据的回顾和即将到来的暗星搜索

Review of Observational Evidence for Dark Matter in the Universe and in upcoming searches for Dark Stars

Katherine Freese

摘要:

在过去的十年里,一个共识的图景已经出现,即宇宙的大约四分之一由暗物质组成。综述了暗物质存在的观测证据:星系自转曲线、弱透镜测量、星系团中的热气、原初核合成和微波背景实验。此外,一个新的研究路线的暗星,这表明,第一个恒星存在于宇宙中的动力是由暗物质加热,而不是通过融合:观察发现暗物质的可能性,以这种方式进行了讨论。

英文摘要:

Over the past decade, a consensus picture has emerged in which roughly a quarter of the universe consists of dark matter. The observational evidence for the existence of dark matter is reviewed: rotation curves of galaxies, weak lensing measurements, hot gas in clusters, primordial nucleosynthesis and microwave background experiments. In addition, a new line of research on Dark Stars is presented, which suggests that the first stars to exist in the universe were powered by dark matter heating rather than by fusion: the observational possibilities of discovering dark matter in this way are discussed.
