AST-0307291HaimanThis project will develop observational diagnostics that, when applied to future data, will lead to an understanding of how and when the first generation of stars and quasar black holes emerged in the universe, and what impact these sources had on the proto-galactic gas between redshifts six and thirty. There are three main thrusts, all at the frontiers of current research: 1) what physical processes determine the nature of the first sources of light, 2) how did the earliest massive black holes form, and 3) when and how was the Universe reionized. The results of this research, from semi-analytical and numerical techniques, concentrating on observational tests capable of distinguishing between competing theoretical models, will be indispensable in the interpretation of the results from a wide array of current and planned ground-based and space-based instruments.Much of the work will be carried out by a graduate student from an under-represented group, and the project will strengthen ties between the geographically separated institutions involved in the collaboration. Research results will also be incorporated in the many and varied public outreach programs of the Hayden Planetarium.***

AST-0307291海曼该项目将开发观测诊断，当应用于未来的数据时，将导致理解第一代恒星和类星体黑洞如何以及何时出现在宇宙中，以及这些来源对红移6和30之间的原银河系气体产生了什么影响。 有三个主要的推动力，都在当前的研究前沿：1）什么物理过程决定了第一个光源的性质，2）最早的大质量黑洞是如何形成的，3）宇宙何时以及如何被重新电离。 这项研究采用半分析和数值技术，侧重于能够区分相互竞争的理论模型的观测检验，其结果对于解释各种现有和计划中的地基和天基仪器的结果将是必不可少的。该项目将加强参与协作的地理上分散的机构之间的联系。 研究成果也将纳入海登天文馆的许多不同的公共宣传方案中。
