Title: Encapsulating precession in gravitational wave signal models.

Abstract:
The gravitational wave signal from precessing systems (those where the spins of the black holes are misaligned with the orbital angular momentum of the binary) is complicated by oscillations in the amplitude and phase, making such systems difficult to understand and to model. This is further compounded by a scarcity of highly precessing waveforms available in public catalogues, required for studying the merger-ringdown signal. However, as we venture into an era of increasingly sensitive detectors, it is ever more important to have a thorough understanding of precessing systems-- as well as highly accurate, computationally robust models for use in the analysis of gravitational wave signals. I will discuss recent developments and challenges in understanding the phenomenologies of these systems.
