Dr. Christian Ott (California Institute of Technology) will combine the modeling techniques of numerical relativity and of core-collapse supernova theory to study black hole formation in the late stages of the collapse of massive star cores. He and his collaborators intend to establish the dependence of black hole formation on progenitor star mass, rotational configuration, nuclear equation of state, and neutrino luminosity/heating. The aims include constraining the progenitor characteristics that may lead to collapsar-type gamma-ray bursts and improving estimates of the stellar-mass black hole formation rate in the universe.The results of the project will improve knowledge of the connection between core collapse supernovae and black hole production, and should result in improved estimates of the stellar-mass black hole formation rate. Furthermore, gravitational wave signals extracted from the simulations and improved rate estimates for compact binary systems will be made available. This project will contribute to the training of a graduate student in numerical general relativity, supernova theory, and computational physics. The results, codes, and microphysics inputs of the project will be made publically available to facilitate future research and training of students. Visualizations and animations resulting from the simulations will be used in ongoing outreach projects of the group.

加州理工学院的Christian Ott博士将结合数值相对论和核心坍缩超新星理论的建模技术，研究大质量恒星核心坍缩后期黑洞的形成。他和他的合作者打算建立黑洞形成与祖恒星质量、旋转构型、核状态方程和中微子光度/加热的依赖关系。目标包括限制可能导致坍缩型伽玛射线暴的祖先特征，以及改进对宇宙中恒星质量黑洞形成率的估计。该项目的结果将提高对核心坍缩超新星和黑洞产生之间联系的认识，并将导致对恒星质量黑洞形成率的改进估计。此外，从模拟中提取的引力波信号和改进的紧凑型双星系统的速率估计将可用。该项目将有助于培养一名在数值广义相对论、超新星理论和计算物理方面的研究生。该项目的结果、代码和微物理输入将公开，以促进未来的研究和学生的培训。模拟产生的可视化和动画将用于小组正在进行的外展项目。
