内容简介 · · · · · ·

《现代宇宙学》系统地介绍了现代宇宙学的最新进展。从平坦均匀的宇宙（可以用弗里德曼—罗伯逊—沃克度规描述）开始,讲解了暗能量的处理过程,宇宙大爆炸的核合成,重组和暗物质,然后介绍了对平坦均匀宇宙的扰动：宇宙的演化和爱因斯坦—玻尔兹曼方程组,原始膨胀和现代宇宙的形成,以及观测结果如宇宙微波背景的各向异性,红移扭曲和弱透镜化现象等。《现代宇宙学》对宇宙微波背景的声学峰结构,以及用来探测原始引力波的偏振的E/B分解都有较详细的讨论,还包含了一个长的章节专门介绍对日益庞大的宇宙观测数据进行现代分析的技术。每章后都附有该章总结和相关文献。通过学习,读者可以获得从事现代宇宙学研究必须的知识和方法。
