- 요약I provide an introduction to the field of gravitational wave data analysis, including a summary of the history and future of gravitational wave detection, a derivation of wave solutions to the linearized Einstein equations, a discussion of observable parameters of the sources of gravitational waves, how gravitational waves create strain in Michelson interferometers, and how that strain data is analyzed to extract those observable parameters. I present mode-by-mode relative binning, a new algorithm for fast and accurate likelihood estimation for gravitational waveform models with higher modes and precession effects. This method reduces full parameter estimation runtime from weeks to hours. I also discuss a new analytic gravitational waveform model for binaries undergoing small center-of-mass acceleration, including those in hierarchal triple systems. I present a Fisher analysis quantifying the detectability of this acceleration at various source chirp masses. Finally, I demonstrate how multi-messenger measurements of double white dwarf systems can be used to break the degeneracy between chirp mass and the impact of tides on orbital evolution. This can enable measurements of either tidal locking or moment of inertia of the white dwarfs without prohibitively expensive radial velocity measurements.
