Binary black hole systems are among the most interesting and likely sources of gravitational waves for both the current generation of ground-based detectors, such as LIGO, and for the next generation of space-based detectors, such as LISA. Such systems are promising from a detection standpoint because of the huge amount of energy they are believed to release in gravitational waves, making them among the intrinsically brightest gravitational wave emitters in the universe,and detectable to cosmological distances. Little is known, however, about their population, formation, evolution, and gravitational wave production.This research will address certain key aspects of black hole binary systems which are at the current boundary of what is technically feasible and what is needed for successful detection and description of these systems. Work will be initiated to make the numerical simulations of the final plunge of comparable mass black hole binaries run longer and more stably to produce longer and more reliable waveforms for use in data analysis. The goal of this research, which combines analytic and numerical techniques, is to provide a series of increasingly realistic predictions. This research at the Hispanic-serving University of Texas at Brownsville will aid in the further development of a research environment in which both graduate and undergraduate students can flourish as scientists, by exposing them to timely front-line research in the company of leading postdoctoral researchers from around the world. Such an environment is crucial in allowing a traditionally under-represented Hispanic population to participate more fully in the national and international scientific communities.

二元黑洞系统是当前一代地基探测器（如LIGO）和下一代天基探测器（如丽莎）最有趣和最有可能的引力波源之一。从探测的角度来看，这样的系统是有希望的，因为它们被认为在引力波中释放了大量的能量，使它们成为宇宙中本质上最亮的引力波发射器之一，并且可以在宇宙学距离内探测到。 然而，人们对它们的数量、形成、演化和引力波的产生知之甚少，这项研究将解决黑洞双星系统的某些关键方面，这些系统目前在技术上是可行的，需要成功地探测和描述这些系统。 将开始进行工作，使质量相当的黑洞双星最后坠落的数值模拟运行更长和更稳定，以产生更长和更可靠的波形，用于数据分析。这项研究的目标，结合分析和数值技术，是提供一系列越来越现实的预测。 这项研究在西班牙裔服务的得克萨斯大学布朗斯维尔将有助于进一步发展的研究环境中，研究生和本科生都可以蓬勃发展的科学家，通过暴露他们及时的前沿研究公司领先的博士后研究人员来自世界各地。 这样的环境是至关重要的，让传统上代表性不足的西班牙裔人口更充分地参与国家和国际科学界。
