暗能量模型的分类

Taxonomy of Dark Energy Models

V. Motta, Miguel A. García-Aspeitia, A. Hernández-Almada, J. Magaña, Tomás Verdugo

摘要:

宇宙的加速膨胀是过去几十年的主要发现之一,表明存在一种未知的成分:暗能量。它存在的证据正在通过一系列观测实验收集,其测量精度越来越高。然而,解释我们宇宙动力学的最被接受的模型,所谓的Lambda冷暗物质,面临着与这种能量成分的性质有关的几个问题。这导致人们越来越多地探索试图解决这些缺点的替代模式。在这篇评论中,我们简要地总结了一个(非详尽的)列表的暗能量模型以及一些最常用的宇宙学样本的特点。接下来,我们讨论如何使用观测数据约束每个模型的参数。最后,总结了暗能量模型的研究现状。

英文摘要:

The accelerated expansion of the Universe is one of the main discoveries of the past decades, indicating the presence of an unknown component: the dark energy. Evidence of its presence is being gathered by a succession of observational experiments with increasing precision in its measurements. However, the most accepted model for explaining the dynamic of our Universe, the so-called Lambda cold dark matter, face several problems related to the nature of such energy component. This has lead to a growing exploration of alternative models attempting to solve those drawbacks. In this review, we briefly summarize the characteristics of a (non-exhaustive) list of dark energy models as well as some of the most used cosmological samples. Next, we discuss how to constrain each model's parameters using observational data. Finally, we summarize the status of dark energy modeling.
