Abstract

It is known than the inclusion of spatial curvature can modify the evolution of matter perturbations and affect the Large Scale Structure (LSS) formation. We quantify the effects of the nonzero spatial curvature in terms of LSS formation for a cosmological model with a running vacuum energy density and a warm dark matter component. The evolution of density perturbations and the modified shape of their power spectrum are constructed and analyzed.

连续的宇宙常数和具有曲率的温暖暗物质的观测数据约束

摘要

众所周知，包含空间曲率可以修改物质扰动的演变并影响大型结构（LSS）的形成。对于具有运行真空能量密度和温暖暗物质成分的宇宙学模型，我们根据LSS的形成来量化非零空间曲率的影响。构造和分析了密度扰动的演化及其功率谱的修正形状。
