This project will investigate the dynamics of black holes and neutron stars via fully nonlinear numerical simulations in Einstein's general theory of relativity. The aim is to improve current models of gravitational waves from energetic black-hole neutron-star merger events, feeding into the current effort to detect such signals and use the results to probe physics under extreme conditions. We will pay particular attention to the microphysics encoded in the supranuclear matter equation of state and further improve recent efforts to introduce large-eddy modes in general relativity (in order to deal with the development of turbulence during the merger phase).

该项目将通过爱因斯坦广义相对论中的完全非线性数值模拟来研究黑洞和中子星的动力学。其目的是改进目前的高能黑洞中子星合并事件引力波模型，为目前探测此类信号的努力提供信息，并利用结果探索极端条件下的物理学。我们将特别注意编码在状态方程的超核物质的微观物理，并进一步提高最近的努力，在广义相对论中引入大涡模式（为了处理合并阶段的湍流的发展）。
