摘　　要：星系尺度上的暗物质研究通常涉及各种不同的暗物质模型。在这些模型中,冷暗物质模型(CDM模型)受到了广泛关注。基于该理论模型的研究,可以较好地解释星系尺度和宇宙大尺度结构中的一些问题。然而,在研究星系小尺度结构时,存在一些该模型无法解释的观测现象。近年来,玻色-爱因斯坦凝聚暗物质模型(BEC-DM模型)和模糊暗物质模型(FDM模型)作为CDM模型的替代方案,受到了广泛关注和大量研究。在BEC-DM模型中,暗物质粒子被假设为一种处于宏观量子态的玻色子;而FDM模型则将暗物质描述为一个具有波动特性和极小质量的粒子。研究这两种理论模型有助于了解不同理论模型对星系中暗物质密度分布和相关性质的影响。在这一背景下,对星系尺度上的玻色暗物质理论模型及其粒子探测进行了简要概述。回顾了暗物质研究的历史,介绍了暗物质候选粒子及对其的探测方法。重点介绍了BEC-DM模型和FDM模型作为传统CDM模型的替代方案,并探讨了它们在解决问题方面的优势。In the past years,the cold dark matter(CDM)model has been extensively studied and provided a theoretical frameworks which offers an excellent explanation for severa l issues related to galaxies and the large-scale structure of universe.However,there are few challenges currently from observational phenomena in small scale with galaxies in the CDM model’s frameworks.Alternative approaches to the CDM model have been proposed and obtained some considerable attention.These progresses include the Bose-Einstein condensate dark matter(BEC-DM)model and the fuzzy dark matter(FDM)model.In BEC-DM model,dark matter particles are assumed to be a kind of boson in a macroscopic quantum state.On the other hand,the FDM model describes the dark matter as a particle which has wave-like properties and assumes its mass is smaller.Studies on these two theoretical models help us to understand the effects of different theoretical models on the density distribution and related properties of galaxies.This paper reviews the historical developments of dark matter research,introduces several dark matter particle candidates and their detection methods.Particularly,we present a detailed review on detection experiments for axion-like particles.
