关于$Λ$ CDM模型尖点核问题解的评述

Review of solutions to the Cusp-core problem of the $Λ$CDM Model

Antonino Del Popolo, Morgan Le Delliou

摘要:

本文旨在向该领域提出尖点核心问题的概述,包括讨论其主张的解决方案,评估每个解决方案如何令人满意地提供中心密度的描述。无论尖点核问题是否反映了我们对暗物质、引力的性质,以及重子与暗物质在这些尺度上相互作用的影响的把握不足,包括在半解析模型或完全数值代码中,它的解决方案要么表明宇宙学需要范式的改变,要么表明我们在消除$Λ$ CDM范式的更精细细节方面缺乏成功。

英文摘要:

This review aims at proposing to the field an overview of the Cusp-core problem, including a discussion of its advocated solutions, assessing how each can satisfactorily provide a description of central densities. Whether the Cusp-core problem reflects our insufficient grasp on the nature of dark matter, of gravity, on the impact of baryonic interactions with dark matter at those scales, as included in semi-analytical models or fully numerical codes, the solutions to it can point either to the need for a paradigm change in cosmology, or to to our lack of success in ironing out the finer details of the $Λ$CDM paradigm.
