Theoretical Studies of the Early Universe

Silk，Joseph 96-17168 Silk博士将研究理论天体物理学和宇宙学中的几个基本问题，这些问题的重点是宇宙微波背景。一个具有代表性的问题是在不同的宇宙学模型中研究宇宙微波背景辐射的角各向异性，其中微小的观测到的各向异性偏差探索了宇宙大尺度结构的起源。第二个例子是对星系形成和演化的研究。改进全球恒星形成率的模型，并将其应用于圆盘和原星系的早期演化，将有助于预测它们的光度、光谱和化学演化。

Silk, Joseph 96-17168 Dr. Silk will research several fundamental problems in theoretical astrophysics and cosmology that focus on the cosmic microwave background. One representative problem is the study of the angular anisotropy of the cosmic microwave background radiation in different cosmological models, where the small observed deviations from anisotropy probe the origin of the large-scale structure in the universe. A second example is the study of galaxy formation and evolution. Improving models for the global star formation rate and application to the early evolution of disks and protogalaxies will aid predictions of their luminosity, spectral and chemical evolution.
