Distant quasars observed less than one billion years after the Big Bang are ideal tracers for studying the birth of the earliest supermassive black holes, the assembly of the first massive galaxies, and the buildup of the large-scale structures seen in the early Universe. The PIs will perform a detailed characterization of 25 such quasars by analyzing a legacy multi-wavelength dataset collected from the world's largest telescopes, covering a wavelength range from X-ray to radio. This program will advance our understanding of the growth of the first supermassive black holes, their interactions with quasar host galaxies, and the large-scale structures surrounding them. Additionally, they will collaborate with the Flandrau Science Center & Planetarium at the University of Arizona to develop a "fusion-camp" summer program that will have broad impacts on outreach and education.Theoretical models predict that the earliest billion supermassive black holes (SMBHs) form in massive galaxies and inhabit massive dark matter halos. The PIs will analyze a suite of multi-wavelength datasets collected from ALMA, VLA, and ground-based optical and infrared telescopes for a sample of 25 quasars in the epoch of reionization. These data, combined with data that is being collected from JWST, Chandra, and HST, will enable the team to resolve the long-standing question of whether the earliest SMBHs reside in the most massive dark matter halos and inhabit emerging large-scale galaxy overdensities. This program will also allow them to study the assembly of quasar host galaxies, understand the connection between AGN feedback and early massive galaxy formation, and constrain cosmic reionization and metal enrichment in the early Universe.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

大爆炸后不到十亿年的遥远类星体是研究最早的超级质量黑洞的诞生，第一个大型星系的组装以及早期宇宙中看到的大型结构的理想示踪剂。 PI将通过分析从世界上最大的望远镜收集的遗留多波长数据集来对25种此类类星体进行详细表征，涵盖从X射线到无线电的波长范围。该计划将提高我们对第一个超级质量黑洞的增长，与类星体宿主星系的相互作用以及周围的大规模结构的理解。此外，他们将与亚利桑那大学的弗兰德劳科学中心和天文馆合作，开发一个“融合训练营”夏季计划，该计划将对外展和教育产生广泛的影响。理论模型预测，最早的十亿个超级质量黑洞（SMBHS）形式是大型的星系和内人物大规模的深色黑质卤素。 PIS将分析从ALMA，VLA和地面的光学和红外望远镜收集的多波长数据集，以在Revionization时期的25个类星体样本中进行样本。这些数据与从JWST，Chandra和HST收集的数据相结合，将使团队能够解决最早的SMBHS是否居住在最庞大的暗物质Halos中并居住在新兴的大规模银河系中的长期问题。该计划还将允许他们研究Quasar寄主星系的组装，了解AGN反馈与早期大型银河系形成之间的联系，并限制早期宇宙中宇宙的电离和金属丰富。该奖项反映了NSF的法定任务，并通过使用该基金会的知识优点和广泛的影响来评估NSF的法定任务。
