This CAREER award supports an integrated research and education program by the PI and his students at California State University Fullerton (CSUF) aimed at hastening the direct detection of gravitational waves with the Laser Interferometer Gravitational Wave Observatory (LIGO). The research is focused on i) a thorough characterization of the Advanced LIGO instruments, especially the identification and removal of noise artifacts in the data that could mask or mimic potential astrophysical signals, and ii) measurement and analysis of scattered light from optical materials that are important for extending Advanced LIGO's reach. The outreach component of this award will establish a pathway for students at nearby community colleges to learn about and become part of the PI's research group. This project will also increase science literacy through the development and dissemination of educational materials for learning gravitational-wave science in the undergraduate curriculum.Albert Einstein predicted gravitational waves in his 1916 theory of general relativity. Nearly a century later, we are poised to directly detect these waves for the first time, and to observe the universe in an entirely new spectrum. LIGO is an NSF-funded project to measure gravitational waves from astrophysical systems such as colliding black holes and neutron stars. This award supports research to thoroughly characterize the LIGO detectors - work essential for the detection of gravitational waves. In addition, it supports research on optical scatter aimed at assessing and improving the quality of commercial optics that will be required to extend the astrophysical reach of future gravitational-wave detectors. These projects provide increased opportunities for students to participate in cutting-edge research at CSUF, a primarily undergraduate and Hispanic-serving institution. The education and outreach components of this award will engage students, many from groups currently underrepresented in physics and astronomy, in the discovery-ready field of gravitational-wave science.

该职业奖支持PI及其学生在加利福尼亚州立大学富勒顿（CSUF）的一项综合研究和教育计划，旨在通过激光干涉仪重力浪潮天文台（LIGO）直接发现引力波。该研究的重点是i）对先进的Ligo仪器的透彻表征，尤其是可以掩盖或模仿潜在的天体物理信号的数据中的噪声伪像的识别和去除，以及II）ii）对光学材料的测量和分析，对于扩展高级Ligo的覆盖范围很重要。该奖项的外展部分将为附近社区大学的学生建立途径，以学习并成为PI研究小组的一部分。该项目还将通过在本科课程中开发和传播教育材料来提高科学素养。将近一个世纪后，我们准备第一次直接检测到这些波浪，并在全新的范围内观察宇宙。 Ligo是一个由NSF资助的项目，旨在测量来自天体物理系统（例如碰撞黑洞和中子星星）的重力波。该奖项支持研究以彻底表征LIGO探测器 - 对重力波的检测至关重要。此外，它支持对旨在评估和提高商业光学质量的光学散射的研究，以扩大未来重力波探测器的天体物理覆盖范围。这些项目为学生提供了更多的机会参加CSUF的前沿研究，CSUF是一个主要是本科和西班牙裔美国人的机构。该奖项的教育和外展成分将吸引学生，其中许多人来自目前在物理和天文学中的人数不足，在重力波科科学的发现领域。
