摘要
近期温度与偏振的宇宙微波背景数据在估计描述当前所谓标准宇宙学模型的所有参数方面已达到高精度。介绍了来自宇宙微波背景各向异性、星系巡天及其交叉相关的积分萨克斯-沃尔夫效应的最新结果。通过观察宇宙微波背景中的精细特征,例如低多极矩处的功率缺乏、原初功率谱和非高斯性的界限,并辅以星系巡天,我们讨论了暴胀物理和早期宇宙中原始扰动的生成。回顾了粒子物理中三个重要主题:来自宇宙学数据的中微子质量和参数界限、热轴子质量界限以及中子寿命,注意与实验室实验结果进行比较。介绍了旨在检验爱因斯坦等效原理的宇宙偏振旋转分析的最新结果。最后,我们讨论了下一代射电设施对未来宇宙微波背景光谱畸变实验分析改进的展望。
