Cosmic Reionization and its Feedback Effect on Galaxy Formation

这个项目的目的是通过模拟宇宙辐射传输和N体/气体动力学来研究宇宙历史上的再电离时代(EOR)。这将解决冷暗物质模型中再电离理论及其对星系形成的反馈中的前沿问题，以便预测可观察到的特征。其中包括对宇宙“黑暗时代”和EOR的红移21厘米背景的预测，这是目前极具观测价值的一个领域。这项工作的更广泛影响包括对本科生和研究生的培训，以及来自代表性不足群体的个人的参与。

The aim of this project is to investigate the Epoch of Reionization (EOR) in the history of the universe via simulations of cosmological radiative transfer and N-body/gas dynamics. This will address frontier problems in the theory of reionization and its feedback on galaxy formation in the Cold DarkMatter model, in order to predict observable signatures. These will include predictions for the redshifted 21-cm background from the cosmic "Dark Ages" and the EOR, an area of great current observational interest. Broader impacts of the work include training of undergraduate and graduate students, and participation of individuals from underrepresented groups.
