This award supports research within the framework of the LIGO Scientific Collaboration (LSC) and the Compact Binary Coalescence (CBC) analysis group. It includes projects in the area of astrophysical interpretation of gravitational-wave signals from binaries with two compact objects, through both gravitational-wave data analysis and source modeling. Effectively the proposed work focuses on developing a concrete framework and a tool-kit for the processing of CBC detections (or upper limits) in order to extract the maximal available astrophysical information for binaries with compact objects with any mass and spin configuration. The research activity focuses on a number of key questions the answers to which are important for the interpretation of current and future gravitational-wave observations with LIGO. The next few years are very important for the development of gravitational-wave physics and its astronomical interpretation, and this research focuses on ways of maximizing the gain from future detections, but also from upper limits expected to constrain current theories of compact-object formation. This research is of interest to the broader community of compact-object astrophysics in a wide range of contexts: e.g., stellar and binary system evolution, neutron star and black hole formation and evolution, gamma-ray bursts, stellar dynamics of globular clusters and galactic centers, as in the coming years LIGO observations can provide uniquely reliable answers to some of the long-standing questions in astronomy and astrophysics. The Markov Chain Monte Carlo computational tools to be developed in this project will be made available within and outside the LSC, and hence can benefit LSC projects beyond the CBC searches and enhance the research infrastructure for parameter-estimation in other scientific and engineering contexts. Outreach activities take advantage of the existing collaboration with the Adler Planetarium & Astronomy Museum with hundreds of thousands of visitors per year; this connection ensures the broad dissemination of research understanding in the diverse, urban environment of the Chicago metropolitan area.

该奖项支持Ligo Scientific Collaboration（LSC）和紧凑型二元合并（CBC）分析小组的研究。它包括通过重力波数据分析和源建模的两个紧凑物体的重力波信号的天体物理解释领域的项目。有效地，提出的工作着重于开发一个混凝土框架和用于处理CBC检测（或上限）的工具套件，以便为具有任何质量和自旋配置的紧凑物体的二进制物提取最大的可用天体物理信息。研究活动着重于许多关键问题，这些答案对于用Ligo解释当前和未来的重力波观察至关重要。接下来的几年对于重力波物理学的发展及其天文学解释非常重要，这项研究重点是最大程度地利用未来检测的收益，但也从预期的上限限制了紧凑型对象形成的当前理论。这项研究在广泛的环境中更广泛的紧凑型天体物理学社区引起了人们的关注：例如，恒星和二元系统的进化，中子星和黑洞的形成和进化，γ射线爆发，球形簇的恒星动态和银河系中心和银河系中心的恒星动态，就像在未来几年中可以为您提供了一些无关紧要的综合问题，而这些问题是无效的。 Markov Chain Monte Carlo计算工具将在LSC内部和外部提供，因此可以使LSC项目受益于CBC搜索，并增强其他科学和工程环境中参数估计的研究基础架构。外展活动利用了与阿德勒天文馆和天文学博物馆的现有合作，每年成千上万的游客；这种联系可确保在芝加哥大都市地区多样化的城市环境中广泛传播研究理解。
