ABSTRACT

This research paper focuses on optimizing the global placement of gravitational wave (GW) detectors to enhance the sky localization accuracy for GW events. Proposed by Einstein's General Theory of Relativity, gravitational waves carry valuable information about cosmic events such as black hole mergers. The study uses Python and the BILBY framework to simulate various global locations for new GW detectors and specifically evaluates locations in Antarctica, South Africa, and Alaska. By simulating a binary black hole merger event at a set sky location, the study compares the difference in sky localization accuracy between different detector networks to find the optimal one. Results show that adding detectors in Antarctica and South Africa will significantly improve sky localization accuracy. Nevertheless, whether the environment in the areas is suitable for future constructions of detectors remains to be answered.
