The project will model the evolution of matter outflows following the merger of neutron star binaries. The project will stitch together the results from simulations that are valid at different scales, using the output of smaller scale simulations as the input for larger scale simulations. In this way, the project will be able to follow the matter outflows and jets from the initial merger event all the way out to the point where the material interacts with the interstellar medium. The project will be able to predict the electromagnetic signals from the merger and relate them to the initial properties of the binary system. The project will also develop materials for use in public outreach to bring astronomy education to students in kindergarten through high school. This award advances the goals of the Windows on the Universe Big Idea. This project is supported by both the National Science Foundation and the US-Israel Binational Science Foundation to further collaborations between the astrophysical communities in the two countries. The project will start with final snapshots from general relativity simulations of the merger event as initial conditions for general relativistic magnetohydrodynamic (GRMHD) simulations. Similarly, the final snapshots of the GRMHD simulations will be used as initial conditions for the magnetohydrodynamic (MHD) simulations that carry the jets out to distances where it interacts with the interstellar medium. The project will then calculate electromagnetic signals from the simulation results using a radiative transfer code. The simulations will be run on GPUs for increased computational efficiency. The project will also develop "Star Packs" for the Sacramento Library appropriate for K-5 students that can be checked out in libraries. The PI at Purdue will develop instructional materials on gravity and black holes for middle- and high-school students. The Northwestern PI will develop instructional materials for an electro-magnetism class at the high-school level.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.

该项目将在中子星二进制文件的合并后对物质流出的演变进行建模。该项目将使用较小比例模拟的输出作为较大尺度仿真的输入，从不同尺度上有效的模拟将结果拼接在一起。这样，该项目将能够遵循从初始合并事件到材料与星际介质相互作用的地步的问题流出和喷射。该项目将能够预测合并中的电磁信号，并将其与二进制系统的初始属性相关联。该项目还将开发用于公共宣传的材料，以通过高中将天文学教育带给幼儿园的学生。该奖项推动了宇宙中窗户的目标。该项目得到了国家科学基金会和美国 - 以色列双原则科学基金会的支持，以进一步合作，在两国的天体物理社区之间。该项目将从合并事件的一般相对性模拟开始的最终快照开始，作为一般相对论磁性水力动力学（GRMHD）模拟的初始条件。同样，GRMHD模拟的最终快照将用作磁性水力动力学（MHD）模拟的初始条件，该模拟将Jets带到与星际介质相互作用的距离。然后，该项目将使用辐射传输代码从仿真结果中计算电磁信号。这些模拟将在GPU上进行，以提高计算效率。该项目还将为萨克拉曼多图书馆开发“恒星包”，适用于可以在图书馆中签出的K-5学生。普渡大学的PI将为中学和高中生开发有关重力和黑洞的教学材料。西北PI将在高中级为电磁性课程开发教学材料。该奖项反映了NSF的法定任务，并被认为是值得通过基金会的知识分子优点和更广泛的影响评估标准通过评估来支持的。
