Removing degeneracy and multimodality in gravitational wave source parameters
Removing degeneracy and multimodality in gravitational wave source parameters
Quasicircular binary black hole mergers are described by 15 parameters, of which gravitational wave observations can typically constrain only $\ensuremath{\sim}10$ independent combinations to varying degree. In this work, we devise coordinates that remove correlations, and disentangle well- and poorly-measured quantities. Additionally, we identify approximate discrete symmetries in the posterior as …
