四位作者在本书中提出的讲座调查了与宇宙加速膨胀有关的核心主题。第一讲涵盖了宇宙早期的暴胀时期。第二讲围绕着由于神秘的暗能量（通常被解释为宇宙常数）导致的红移z < 1的晚期宇宙加速膨胀。这种加速膨胀的发现依赖于Ia型超新星的数据，所以这第二讲是专门为Ia型超新星的天体物理学和它们在宇宙学观测中的作用。第三讲，寻求暗能量的替代解释，涉及修改后的引力模型。这种理论目前似乎是最严重的竞争对手，以传统的暗能量模型的基础上宇宙常数或其时间依赖的对应物所产生的标量场和第四讲讨论目前可用的统计方法，是不可或缺的宇宙学数据的分析，这使得它们成为现代宇宙学研究的许多结果的必要先决条件。这本书旨在作为研究生和年轻人的切入点。积极的宇宙学研究
The lectures that four authors present in this volume investigate core topics related to the accelerated expansion of the Universe. The first lecture covers the inflationary period in the very early Universe. The second lecture revolves around the accelerated expansion of the late Universe at redshifts z < 1 due to the enigmatic dark energy that is commonly interpreted as a cosmological constant. The discovery of this accelerated expansion relied on data from type Ia supernovae, so this second lecture is dedicated to the astrophysics of type Ia supernovae and their role in cosmological observations. The third lecture, which seeks alternative explanations of dark energy, deals with modified gravity models. Such theories presently appear to be the most serious competitors to conventional dark-energy models based on a cosmological constant or its time-dependent counterparts arising from a scalar field And the fourth lecture discusses currently available statistical methods that are indispensable for the analysis of cosmological data, thus making them necessary prerequisites for many of the results of modern cosmological research This book is intended to serve as an entry point for graduate students and young researchers into active cosmological research
