Research will be performed on fundamental and relevant problems in the areas of cosmology and galaxy formation. Emphasis will be placed on improving models for the global star formation rate in disk galaxies and developing this approach to be applicable to the early evolution of disks and to protogalaxies. This will enable one to predict their luminosity, spectral and chemical evolution. A second investigation will be of the angular anisotropy of the cosmic microwave background radiation in open cosmological models. Small deviations from anisotropy are inevitable and probe the origin of the large-scale structure in the Universe; detailed predictions are necessary to compare with experiments. The Principal Investigator is recognized as one of the world leaders in theoretical cosmology and extragalactic astronomy.

将对以下方面的基本问题和相关问题进行研究： 宇宙学和星系形成的领域。 重点将 放在改进全球星星形成率的模型上， 盘星系和发展这种方法适用于 盘的早期演化和原星系。 这将使 一个是预测它们的光度光谱和化学演化 第二个研究将是角各向异性的 开放宇宙学模型中的宇宙微波背景辐射。 与各向异性的微小偏差是不可避免的， 宇宙中大尺度结构的起源;详细 预测必须与实验进行比较。 首席研究员被公认为世界上 理论宇宙学和河外天文学的领导者。
