Next steps in binary simulations

目前正在运行的地面引力波探测器可能很快就会打开一扇了解宇宙的新窗口。引力波观测有可能揭示各种现象，如伽马射线爆发和黑洞碰撞。要充分利用这些丰富的信息，需要对可能的来源进行理论建模。这些模型对于将实验数据与物理信息提取的预测对峙将是至关重要的。本奖项支持的研究正是在对相关现象建模和接触数据分析工作的背景下，寻求对能够产生最有可能检测到的信号的二进制系统进行数值建模。这样的建模将结合新的技术，以获得系统的稳健和准确的描述，并有效地利用现在和未来可用的计算资源。将讨论模型和分析之间的界面上的一些问题，这些问题限制了所需模型的敏锐性，以及理解如何优化模型提供的逐渐可用的信息的有用性。这项研究将为一个重要的科学问题提供先进的数值技术，并有助于在引力波源模拟和引力波数据分析之间的接口上不断发展的领域。年轻的研究人员将在这一研究领域接受培训。

Ground-based gravitational wave detectors now operating may soon open a new window on the universe. Gravitational wave observations have the potential to shed light on a variety of phenomena such as gamma ray bursters and black hole collisions. To exploit fully this rich information requires theoretical modeling of possible sources. These models will be crucial for confronting experimental data with predictions for the extraction of the physical information. It is within the context of both modeling relevant phenomena and making contact with the data analysis effort that the research supported by this award seeks to numerically model binary systems able to produce the most likely detectable signals. Such modeling will incorporate novel techniques to obtain a robust and accurate description of the system and to efficiently exploit present and future available computational resources. A number of issues at the interface between model and analysis which constrain the sharpness of the required models as well as understanding how to optimize the usefulness of the gradually available information provided by the models will be addressed. This research will yield advanced numerical techniques for an important scientific problem, and aid in the growing field at the interface between simulations of gravitational wave sources and analysis of gravitational wave data. Young researchers will be trained in this area of research.
