Workshop on the Interface between Post-Newtonian Theory and Numerical Relativity

该奖项为一个研讨会提供差旅支持，该研讨会旨在聚集后牛顿(PN)理论和数值相对论(NR)的活跃研究人员，以便在这两种方法之间的接口上取得进展，目标是开发对致密天体的双星系统的激励、合并和衰变的无缝描述。需要解决的问题包括(I)NR模拟的PN初始数据，(Ii)将PN和NR重力波形拼接在一起的方法，(Iii)NR初始数据的PN诊断工具的使用，以及(Iv)PN序列不同表示的相对性能。研讨会将于2007年2月8日至11日在圣路易斯的华盛顿大学举行。研讨会的形式将是上午的讲座和下午的工作会议，在这些会议上，工作人员可以分享想法、辩论、运行NR代码、进行PN展开、模拟数据分析等。最近在使用数值相对论模拟黑洞和中子星的激发和合并方面取得的突破，以及对全引力波信号的准确模板的持续需求，以支持在LIGO、Virgo或LISA等干涉仪上的数据分析，这使得如何将描述激发波早期部分的后牛顿(PN)方法与数值相对论(NR)方法联系起来这一问题变得更加紧迫。它们描述了最终的轨道、合并和环流。研讨会将包括博士后和研究生的参与，因此它将对该领域未来科学家的教育和培训产生影响。

This award provides travel support for a workshop intended to bring together active researchers in Post-Newtonian (PN) theory and in Numerical Relativity (NR) in order to make progress on the interface between the two approaches, with the goal of developing a seamless description of the inspiral, merger and ringdown of binary systems of compact objects. Among the problems to be addressed are (i) PN initial data for NR simulations, (ii) ways to stitch together PN and NR gravitational waveforms (iii) use of PN diagnostic tools for NR initial data and (iv) relative performance of different representations of PN series. The workshop will be held at Washington University in St. Louis, February 8 - 11, 2007. The format of the workshop will be lectures in the morning that highlight the central questions and problems, and working sessions in the afternoon where workers can share ideas, argue, run NR codes, do PN expansions, simulate data analysis, etc.Recent breakthroughs in simulating the inspiral and merger of black holes and neutron stars using numerical relativity and the continuing need for accurate templates for the full gravitational-wave signal to support data analysis at interferometers like LIGO, VIRGO or LISA, have made more pressing the question of how to link post-Newtonian (PN) methods, which describe the early part of the inspiral, with the methods of numerical relativity (NR), which describe the final orbits, the merger and the ringdown. The workshop will include the participation of postdocs and graduate students, so it will have an impact on the education and training of future scientists in this field.
