Gravitational waves have the potential to expand astronomy into an entirely new regime, providing information about the dynamics and central engines of astrophysical events that are not available by any other means. Combining gravitational waves with electromagnetic observations through multi-messenger astronomy will maximize the information available and allow scientific discoveries that would not be possible with either alone. Our research focuses on three specific projects. The first of these involves searches for gravitational waves in coincidence with short duration radio pulses. Radio signals are a potentially crucial component of a full program of multi-messenger astronomy in the advanced detector era. In some cases, radio emission may be the only observable signal in the direction of the Earth aside from gravitational waves. Using pulses from currently existing Green Bank Telescope pulsar surveys as external triggers in LIGO/Virgo searches will allow us to probe deeper into our current data and set the stage for future coincident analyses between radio signals and gravitational waves. The other direction in which multi-messenger astronomy can be performed, and our second area of focus, entails the follow-up of potential gravitational wave triggers with instruments looking for other astronomical messengers. Regardless of the method employed to detect a signal, having the best data possible to work with will be critical in successfully detecting gravitational waves. Thus, the third area of focus is in detector characterization, the understanding and mitigation of transient disturbances in the detector that may be confused with astrophysical signals, including developmental studies, as well as well as work maintaining software and validating the calibration of the instruments.Direct confirmation of Einstein's general theory of relativity through the observation of gravitational waves would be a major accomplishment of 21st century physics, with consequences in gravitational theory as well as astronomy and astrophysics. Validating this observation with coincident emission of photons from the same event would increase our confidence in such an observation. Additionally, a multi-messenger approach to astronomy, "hearing the universe" through gravitational waves as well as seeing it through optical, x-ray or radio astronomy, will allow us to gain a more complete scientific picture of the sky around us, potentially including such phenomena as gamma-ray bursts and supernovae. Since the research is carried out at a primarily undergraduate institution and fully integrates undergraduate researchers, this grant also facilitates the critical task of preparing the next generation of physicists.

引力波有潜力将天文学扩展为一个全新的制度，提供有关天体物理事件的动态和中央引擎的信息，这些动态和中央引擎无法通过任何其他方式获得。通过多通信者天文学结合引力波与电磁观测，将最大程度地提高可用信息，并允许单独使用的科学发现。我们的研究重点是三个特定项目。其中的第一个涉及搜索与持续时间短的无线电脉冲巧合的重力波。无线电信号是高级探测器时代多通间天文学的完整程序的潜在至关重要的组成部分。在某些情况下，无线电发射可能是唯一一个可观察到的信号，除了重力波。使用当前现有的绿色银行望远镜脉冲星调查的脉冲作为Ligo/处女座搜索中的外部触发器，将使我们能够对当前数据进行更深入的探讨，并为未来的无线电信号和引力波之间的复合分析奠定了基础。可以执行多情绪天文学的另一个方向，而我们的第二个重点领域则是对潜在的引力波触发器的随访，并使用寻找其他天文学使者的工具。无论用于检测信号的方法如何，拥有可能使用的最佳数据对于成功检测重力波至关重要。 因此，重点的第三个领域是在探测器表征上，对检测器中的瞬时干扰的理解和缓解可能与天体物理信号混淆，包括发育研究，以及维持软件的工作以及验证仪器校准的工作。直接确认Einstein与Einstein的相对性的一般性理论，以及与重力的浪潮相对的一般理论，这是21级的范围，这是21级的浪潮，这是21级的浪潮。天文学和天体物理学。 通过同一事件从同一事件中验证光子的一致发射的观察结果将增加我们对这种观察的信心。 此外，通过重力波，通过光学，X射线或射电天文学看到的“听到宇宙”的多理智方法，“听到宇宙”，将使我们能够获得周围天空的更完整的科学景象，包括诸如伽马射线爆发和超级新闻等现象。由于该研究是在主要的本科机构进行的，并完全整合了本科研究人员，因此该赠款还促进了准备下一代物理学家的关键任务。
