- 요약The joint detection of GW170817 and the subsequent kilanova between the LIGO Collaboration, Swift, Fermi, INTEGRAL, and many other observatories heralded our current era of multimessenger astronomy. With a non-Gaussian transient causing initial issues with the detection of GW170817, this detection proved not only the necessity of prompt detection of such events, but also the importance of low-latency data quality information. However, high-latency gravitational wave searches continue to uncover further detections in archival data which were missed in the initial real-time search at the cost of millions of computing hours.This dissertation focuses on the improvements to both the GstLAL detection pipeline, and the statistical data quality pipeline iDQ to support the analysis of gravitational waves exclusively in low-latency. This includes discussion of general improvements to both pipelines ahead of LIGO's fourth observing run, and initial results from this period. We then go further to explore new features of the low-latency GstLAL pipeline which both provide live measures of its sensitivity, and increase the sensitivity of its final results without re-filtering any of the data as high-latency pipelines do. We also discuss a new method applied to iDQ which can trace non-Gaussian transients to their sources in the interferometer, and demonstrate how this can be applied in low-latency follow-up of gravitational wave events. Finally, we demonstrate how the sensitivity of future generation of gravitational wave detectors will support the measurement and constraint of neutron star's radii and equation of state with gravitational waves alone.
