This project will create a Theoretical and Computational Astrophysics Network with major nodes at the University of Maryland, the Georgia Institute of Technology, and Yale University to advance the theory of formation, fueling, and feedback of supermassive black holes (SMBHs). The project proposes to accomplish this task by linking computational codes simulating large-scale SMBH phenomena (i.e. cosmological gravitational collapse and AGN jets) to the small-scale phenomena (i.e. SMBH formation and feedback on galactic structure). For the "formation stage", the project intends to answer the question of how the first black hole (BH) seeds formed within the early universe by numerically simulating the coupling of large-scale baryonic structures and dark-matter halos to small-scale collapse of primordial gas disks into massive BH seeds. For the "fueling stage" the project aims to explore the growth of the BH seed into a SMBH from galaxy-scale accretion flows to SMBH mergers. Finally, for the "feedback stage" the goal is to explore the mechanisms by which the SMBHs at the centers of active galactic nuclei (AGN) couple to the inter-cluster plasma on cosmological scales. The network will contribute to scientific workforce development through the involvement of undergraduate students, graduate students and postdocs. The project will communicate results to the public through development of a 3-D visualization taking the viewer on a journey to witness the birth and growth of a SMBH and its influence on the cosmological environment.

该项目将在马里兰大学，佐治亚大学理工学院和耶鲁大学建立一个理论和计算天体物理学网络，并通过主要节点和耶鲁大学建立主要节点，以促进地层，加油理论和超级质量黑洞（SMBHS）的反馈。 该项目建议通过将计算代码联系起来，将计算代码链接到模拟大规模SMBH现象（即宇宙学引力崩溃和AGN Jets）与小规模现象（即SMBH形成和银河系结构的反馈）。 对于“地层阶段”，该项目打算通过数值模拟大规模的Baryonic结构的耦合以及深色模型对原始气盘中的小规模崩溃，将第一个黑洞（BH）种子在早期宇宙中形成的问题。 对于“加油阶段”，该项目旨在探索BH种子的生长，从星系尺度的积聚流到SMBH合并。 最后，对于“反馈阶段”，目标是探索活性银河核（AGN）夫妇中心的SMBHS到宇宙学量表上群群等离子体的机制。 该网络将通过本科生，研究生和博士学位的参与来为科学劳动力发展做出贡献。 该项目将通过开发3-D可视化的发展将结果传达给公众，这使观众踏上了见证SMBH的出生和成长及其对宇宙学环境的影响的旅程。
