Title: Understanding precessing binary-black-hole systems
Accurate signal models are essential in the analysis of gravitational wave events, from parameter estimation to astrophysical interpretation and tests of general relativity. As detectors get increasingly advanced it becomes ever more crucial to develop precision models of signals from a wide range of physical systems, including black-hole-binaries where the spins are not aligned with the orbital angular momentum— precessing binaries. Evidence for a population of such systems has already been seen during the third observing run of the LVK and this is expected to become stronger in the upcoming run. I will discuss recent developments that have resulted in the first complete inspiral-merger-ringdown model of the gravitational wave signal from a precessing binary where the precession effects have been tuned to numerical relativity through merger and ringdown as well as a more complete understanding of the phenomenology of such systems.
