论文摘要
在$λ$ CDM模型的扩展中,允许中微子或温暖的暗物质的存在,我们发展了分析宇宙学的扰动理论。它涵盖了所有空间尺度,其中弱重力场状态代表有效的近似。离散的颗粒 - 不均匀重力场的来源 - 可能是相对论的。与先前研究的非依赖性问题的情况相似,Yukawa的相互作用范围自然纳入了一阶标量公制校正中。
Within the extension of the $Λ$CDM model, allowing for the presence of neutrinos or warm dark matter, we develop the analytical cosmological perturbation theory. It covers all spatial scales where the weak gravitational field regime represents a valid approximation. Discrete particles - the sources of the inhomogeneous gravitational field - may be relativistic. Similarly to the previously investigated case of nonrelativistic matter, the Yukawa interaction range is naturally incorporated into the first-order scalar metric corrections.
