论文摘要
宇宙的历史及其塑造它的力是用宇宙地图编码的。从理解这些地图，我们就可以洞悉其他方式无法访问的自然。不幸的是，基本物理学与宇宙可观察物之间的联系通常留给专家（和/或计算机），从而使从数据的一般课程晦涩到许多粒子理论家。幸运的是，控制粒子相互作用的相同基本原理，例如地方性和因果关系，也控制整个宇宙的演变以及数据中新物理学的表现。通过关注这些原则，我们可以更直观地了解下一代宇宙调查将如何告知我们对基本物理学的理解。在这些讲座中，我们将通过三个示例探索理论与数据之间的这种关系：光文（$ n _ {\ rm eff} $）和宇宙微波背景（CMB），中微子质量和CMB的重力镜头，以及原始非高斯性非高斯和分布银河。我们将讨论这些信号的理论基础，以及进行测量的现实世界障碍。
The history of the Universe and the forces that shaped it are encoded in maps of the cosmos. From understanding these maps, we gain insights into nature that are inaccessible by other means. Unfortunately, the connection between fundamental physics and cosmic observables is often left to experts (and/or computers), making the general lessons from data obscure to many particle theorists. Fortunately, the same basic principles that govern the interactions of particles, like locality and causality, also control the evolution of the Universe as a whole and the manifestation of new physics in data. By focusing on these principles, we can understand more intuitively how the next generation of cosmic surveys will inform our understanding of fundamental physics. In these lectures, we will explore this relationship between theory and data through three examples: light relics ($N_{\rm eff}$) and the cosmic microwave background (CMB), neutrino mass and gravitational lensing of the CMB, and primordial non-Gaussianity and the distribution of galaxies. We will discuss both the theoretical underpinnings of these signals and the real-world obstacles to making the measurements.
