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.

该项目将模拟中子星星双星合并后物质外流的演变。该项目将把不同尺度下有效的模拟结果缝合在一起，使用较小尺度模拟的输出作为较大尺度模拟的输入。通过这种方式，该项目将能够跟踪从最初的合并事件到物质与星际介质相互作用的物质流出和喷射。该项目将能够预测合并产生的电磁信号，并将其与双星系统的初始属性联系起来。该项目还将编制用于公共宣传的材料，向幼儿园至高中的学生提供天文学教育。该奖项推进了Windows on the Universe Big Idea的目标。该项目得到了美国国家科学基金会和美国-以色列两国科学基金会的支持，以进一步加强两国天体物理界之间的合作。该项目将从合并事件的广义相对论模拟的最终快照开始，作为广义相对论磁流体动力学（GRMHD）模拟的初始条件。同样，GRMHD模拟的最终快照将用作磁流体动力学（MHD）模拟的初始条件，该模拟将喷流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模拟结果中计算电磁信号。模拟将在GPU上运行，以提高计算效率。该项目还将为萨克拉门托图书馆开发适合K-5学生的“星星包”，这些学生可以在图书馆借阅。普渡大学的PI将为初中和高中学生开发关于引力和黑洞的教学材料。西北PI将为高中水平的电磁学课程开发教学材料。该奖项反映了NSF的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
