The emerging field of gravitational-wave (GW) astronomy has entered an exciting phase with large-scale interferometric GW detectors (LIGO, GEO600, TAMA300, and Virgo) taking data in either science or engineering runs. The LIGO project completed its landmark fifth science run (S5) in 2007 and will begin a new one (S6) in summer 2009. This award supports research in three critical areas relevant to LIGO data analysis: (i) searches for a cosmological or astrophysical GW background, (ii) a statistical search for GWs from gamma-ray bursts, and (iii) detector characterization.The first project will improve our sensitivity to GW backgrounds that have a non-uniform distribution of power on the sky. The second will develop methods to optimally use the information provided by NASA missions (Swift and Fermi) in GW searches. The third will use advanced data mining methods to develop a better understanding of real data, which will benefit the sensitivity of all GW searches. Three graduate students will receive direct training in GW data analysis, thus adding to the growing community of researchers in this emerging field. Since the University of Texas at Brownsville (UTB) is an Hispanic serving institution, the research activities will expose students who are traditionally under-represented in the areas of science and technology to forefront scientific research. On-going major outreach programs at UTB will be able to leverage this research, creating awareness among high-school students about exciting scientific projects such as LIGO.

新兴的引力波（GW）天文学领域已经进入了一个令人兴奋的阶段，大型干涉GW探测器（LIGO，GEO600，TAMA 300和Virgo）在科学或工程运行中获取数据。 LIGO项目在2007年完成了具有里程碑意义的第五次科学运行（S5），并将在2009年夏季开始新的一次科学运行（S6）。该奖项支持与LIGO数据分析相关的三个关键领域的研究：（i）宇宙学或天体物理学GW背景的搜索，（ii）来自伽马射线爆发的GW的统计搜索，以及（iii）探测器表征。第一个项目将提高我们对GW背景的灵敏度，这些背景在天空中具有不均匀的功率分布。 第二个项目将制定方法，在GW搜索中最佳地使用NASA任务（Swift和Fermi）提供的信息。 第三个将使用先进的数据挖掘方法来发展对真实的数据的更好理解，这将有利于所有GW搜索的灵敏度。三名研究生将接受GW数据分析的直接培训，从而增加了这一新兴领域不断增长的研究人员群体。 由于德克萨斯大学布朗斯维尔分校（UTB）是一所西班牙裔服务机构，研究活动将使传统上在科学和技术领域代表性不足的学生接触前沿科学研究。 UTB正在进行的主要推广计划将能够利用这项研究，在高中学生中建立对LIGO等令人兴奋的科学项目的认识。
