The Laser Interferometer Gravitational-wave Observatory (LIGO) consists of 4 km baseline detectors in Livingston, Louisiana, and Hanford, Washington, and an additional 2 km detector in Hanford. LIGO's operating principle is to use precision laser interferometry to measure the relative motion of seismically-isolated test mass mirrors due to the extremely small forces from gravitational waves (GW's) emitted by distant astrophysical events. This project at Louisiana State University (LSU) supports experimental work to reduce the effects of ground disturbances on the detector and on future improved detectors. It also supports the development of software that analyzes and monitors the data to look for astrophysical GW sources and to understand and improve the detector.In a broad context, this project involves LSU faculty, postdocs, graduate students and undergraduates at LIGO, bringing LSU people the benefits of working with experienced LIGO and LIGO Scientific Collaboration (LSC) scientists, and with apparatus that allows an excellentpossibility of significant scientific discovery. LSU is located approximately 35 miles from LIGO Livingston Observatory (LLO) and has a long-term collaborative relationship with LIGO as a member of the LIGO Scientific Collaboration. LSU shares its libraries, networking facilities, and workshops. The impact on LLO, a close and extensive relationship with a nearby research university, is expected to be strengthened with continued collaboration.

激光干涉仪引力波天文台（LIGO）包括位于路易斯安那州利文斯顿和华盛顿汉福德的4公里基线探测器，以及位于汉福德的另一个2公里探测器。LIGO的工作原理是使用精密的激光干涉测量法来测量地震隔离的测试质量镜的相对运动，这是由于遥远的天体物理事件发出的引力波（GW）产生的极小的力。 路易斯安那州立大学的这一项目支持减少地面干扰对探测器和未来改进的探测器的影响的实验工作。 它还支持开发软件，分析和监测数据，寻找天体物理GW源，并了解和改进探测器。在广泛的背景下，该项目涉及LSU教师，博士后，研究生和LIGO的本科生，使LSU人员与经验丰富的LIGO和LIGO科学合作（LSC）科学家合作的好处，and with apparatus设备that allows允许a excellent优秀possibility可能性of significant重大scientific科学discovery发现. 路易斯安那州立大学距离LIGO利文斯顿天文台（LLO）约35英里，作为LIGO科学合作组织的成员，与LIGO有着长期的合作关系。 路易斯安那州立大学共享其图书馆，网络设施和研讨会。 对LLO的影响，与附近的一所研究型大学建立了密切而广泛的关系，预计将通过持续的合作得到加强。
