This study harnesses the predictive power of numerical relativity simulations to investigate extreme astrophysical systems. The work is organized in three activities areas: 1) compact object binaries and a sandbox of simulation data, 2) massive black holes in astrophysical environments, and 3) compact object mergers in scalar-tensor theories of gravity. The effort involves postdocs and students working in an interdisciplinary environment fostering interactions and collaborations with researchers in computing science and engineering.Numerical relativity has truly become a tool of discovery, enabling conversations between astrophysics and scientists from many areas focussed on the intricacies of analyzing interferometric detector data. This study is aimed at enhancing the impact numerical relativity is having on gravitational wave physics, astrophysics and cosmology. The work focuses on multi-scale/multi-physics problems where gravity displays its strongest grip, situations such as the collision of black holes in astrophysical environments for which the tools of numerical relativity provide the only avenue to gain new insights and to make observational predictions.

这项研究利用数值相对论模拟的预测能力来研究极端的天体物理系统。这项工作分为三个活动领域：1）紧凑型物体双星和模拟数据沙箱，2）天体物理环境中的大质量黑洞，以及3）引力标量张量理论中的紧凑型物体合并。这项工作涉及博士后和学生在一个跨学科的环境中工作，促进与计算科学和工程研究人员的互动和合作。数值相对论已经真正成为一种发现的工具，使天体物理学和来自许多领域的科学家之间的对话集中在分析干涉探测器数据的复杂性上。这项研究的目的是增强数值相对论对引力波物理学、天体物理学和宇宙学的影响。这项工作的重点是多尺度/多物理问题，其中重力表现出最强的抓地力，例如在天体物理环境中黑洞碰撞的情况，数值相对论工具提供了获得新见解和进行观测预测的唯一途径。
