On the Current and Future Capability of Parameter Estimation Methods of Compact Binary Coalescence events through measured Gravitational Waves via LIGO, VIRGO, and Cosmic Explorer

Other Versions:

Abstract:: We introduce, understand, and interpret parameter estimation (PE), examining its role in analyzing Compact Binary Coalescence events (CBC) via their emission of Gravitational Waves (GW) and the measured GW strains by instruments such as LIGO, VIRGO, and the future detector Cosmic Explorer (CE). We explain and list all fifteen parameters that characterize of CBC. Understanding and looking at current methods of parameter estimation \textit{(Bayesian inference, Fisher Matrix)}, we investigate how each method is currently used \textit{(Bilby)}, future possibilities of the methods via machine learning \textit{(Dingo)}, and advancements in detectors \textit{(Cosmic Explorer)}. Conducting a comparative quantitative analysis with a methodology considering the speed, accuracy, and precision of the different methods and detectors, we aim to assess their efficiency and capabilities, offering insight on the future of PE of CBC events. We evaluate simulated events developed from a \textbf{\textit{ IMRPhenomPv2}} waveform approximation and similar phenomenological frequency-domain waveform approximations to develop our injections of a full spectrum of CBC events. Doing this allows us to measure greater accuracy, precision, and characterization of potential strengths and weaknesses of each waveform model and detector.
