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.

该奖项为旨在汇集后牛顿（PN）理论和数值相对论（NR）的活跃研究人员的研讨会提供旅行支持，以便在两种方法之间的接口上取得进展，目标是开发紧凑物体的二进制系统的inspiral，合并和ringdown的无缝描述。其中要解决的问题是（i）PN初始数据NR模拟，（ii）的方式缝合在一起PN和NR重力波形（iii）使用PN诊断工具NR初始数据和（iv）PN系列的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，强调中心问题和问题，下午的工作会议，工人可以分享想法，争论，运行NR代码，做PN扩展，模拟数据分析，最近在利用数值相对论模拟黑洞和中子星的螺旋和合并方面的突破，以及对精确模板的持续需求，波信号来支持像LIGO、VIRGO或丽莎这样的干涉仪的数据分析，使得如何将描述螺旋上升早期部分的后牛顿（PN）方法与描述最终轨道、合并和衰荡的数值相对论（NR）方法联系起来的问题变得更加紧迫。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。
