This award supports continuation of the activities of the PI's group in the LIGO Scientific Collaboration (LSC). These activities include support of the Matlab data analysis infrastructure, used by all the LSC data analysis groups, development of automatic and remote science monitoring capabilities and tools, production of simulations used by the LSC burst source analysis group for validation and verification of the analysis chain, and the astrophysical interpretation of the burst source search results.LIGO (Laser Interferometer Gravitational-wave Observatory) is currently taking data at design sensitivity---an ability to detect gravitational waves which change the four kilometer length of a LIGO instrument by less than one one-thousanth of a proton diameter. Possible astronomical sources such as star collapse or black hole collisions could produce bursts of gravitational waves. This award supports essential components for analysis of LIGO's data, especially with respect to sources producing bursts.

该奖项支持PI团队在LIGO科学合作组织（LSC）中继续开展活动。这些活动包括支持所有LSC数据分析小组使用的Matlab数据分析基础设施，开发自动和远程科学监测能力和工具，制作LSC突发源分析小组用于验证和核实分析链的模拟，以及对爆源搜索结果的天体物理学解释（激光干涉仪引力波天文台）目前正在以设计灵敏度获取数据-探测引力波的能力，这种引力波使LIGO仪器的4公里长度变化不到质子直径的千分之一。可能的天文学来源，如星星坍缩或黑洞碰撞，可能会产生引力波的爆发。该奖项支持LIGO数据分析的重要组成部分，特别是关于产生爆发的来源。
