宇宙学中标准模型的检验与问题

Tests and problems of the standard model in Cosmology

Martin Lopez-Corredoira

摘要:

标准$Λ$ CDM宇宙学模型的主要依据是:1)星系的红移是宇宙膨胀加奇异运动的结果; 2)宇宙微波背景辐射及其各向异性是由物质与辐射退耦的高能原初宇宙产生的; 3)用原初核合成解释了轻元素的丰度分布; 4)星系的形成和演化只能在暴胀+暗物质+暗能量的情况下用引力来解释。对这些想法进行了大量的测试,虽然标准模型在拟合许多观测结果方面效果很好,但也有许多数据存在明显的警告,需要理解。在本文中,我对这些测试和问题进行了回顾,并提供了一些替代模型的例子。

英文摘要:

The main foundations of the standard $Λ$CDM model of cosmology are that: 1) The redshifts of the galaxies are due to the expansion of the Universe plus peculiar motions; 2) The cosmic microwave background radiation and its anisotropies derive from the high energy primordial Universe when matter and radiation became decoupled; 3) The abundance pattern of the light elements is explained in terms of primordial nucleosynthesis; and 4) The formation and evolution of galaxies can be explained only in terms of gravitation within a inflation+dark matter+dark energy scenario. Numerous tests have been carried out on these ideas and, although the standard model works pretty well in fitting many observations, there are also many data that present apparent caveats to be understood with it. In this paper, I offer a review of these tests and problems, as well as some examples of alternative models.
