Abstract
A phenomenon that stands on the brink of revolutionizing our understanding of the cosmos, gravitational waves are disturbances in space-time, propagating from massive binary systems at the speed of light. Transparent to matter particulates and other obstacles that would normally hinder traditional, light-based observatories, gravitational waves hold the potential to provide clear, undistorted data on everything from the Big Bang to black holes. This investigation focuses on analyzing the impact the inclusion of a fourth detector in Japan will have on the present methods of analysis. The interferometer, called KAGRA, supplements two existing observatories in the United States and one in Italy, and is expected to reach completion by the beginning of the next decade. Previous investigations into the addition of a detector in India have demonstrated improvements in determining the location of a gravitational wave in the sky as well as the masses of the source. We hope to demonstrate similar improvements with the addition of KAGRA. Ultimately, the work done through this investigation will provide a foundation for future research in anticipation of a fully operational KAGRA interferometer.
