The research program at Carleton has a history of applying novel statistical strategies for parameter estimation and the analysis of data from LIGO. The Carleton team and its collaborators have made significant progress in developing methods for binary inspiral gravitational wave event detection. The group's on-going research is in the development of programs for even more complex binary inspiral signals, including the plunge, and the ringing of the newly formed black hole as well as supernova produced signals. When detection occurs, parameter estimation will provide the path toward astrophysics, and the Carleton-developed routines will be critical in that task. Additionally, the Carleton group searches for sources of noise that produce deleterious effects. Carleton develops vetoes for binary inspiral-like events produced by local environmental or detector disturbances; the group also assists the European Virgo detector in their burst and binary inspiral veto development, and will continue to do so with Advanced Virgo. Carleton is a leader in producing future scientists. This project will provide research opportunities to students with interests in physics and statistics, and help to train them to become the next generation of scientists. Carleton students are eager to participate in exciting research, and their interest in gravitational wave astronomy is large. The computational methods developed by the PI and collaborators have had significant influence in other fields, with applications in cosmic microwave background analyses, noisy chaotic systems, and proposed space-based gravitational wave detectors. Carleton faculty, including the PI, are also active in scientific outreach. High school students and teachers are regularly exposed to the wonder and significance of LIGO's research, and this outreach creates much excitement for science.

卡尔顿的研究项目在应用新颖的统计策略进行参数估计和LIGO数据分析方面有着悠久的历史。卡尔顿团队及其合作者在开发双激发引力波事件探测方法方面取得了重大进展。该小组正在进行的研究是开发更复杂的双星激励信号的程序，包括暴跌，新形成的黑洞的铃声以及超新星产生的信号。当探测发生时，参数估计将为天体物理学提供路径，而卡尔顿开发的例程将在这项任务中至关重要。此外，卡尔顿小组寻找产生有害影响的噪声源。卡尔顿发展了由局部环境或探测器扰动产生的二元类吸气事件的否定词；该小组还协助欧洲处女座探测器在他们的爆发和二进制灵感否决的发展，并将继续这样做与先进处女座。卡尔顿大学在培养未来科学家方面处于领先地位。该项目将为对物理和统计学感兴趣的学生提供研究机会，帮助他们成为下一代科学家。卡尔顿的学生渴望参与激动人心的研究，他们对引力波天文学的兴趣很大。PI及其合作者开发的计算方法在其他领域具有重大影响，应用于宇宙微波背景分析，嘈杂混沌系统和拟议的天基引力波探测器。卡尔顿大学的教职员工，包括PI，也积极参与科学推广活动。高中学生和老师经常接触到LIGO研究的奇迹和意义，这种延伸为科学创造了很多兴奋。
