Phenomenological time domain model for dominant quadrupole gravitational wave signal of coalescing binary black holes

In this work we present IMRPhenomTP, a time domain phenomenological model for the dominant l=2, m=|2| modes of coalescing black hole binary systems and its extension to describe general precessing systems within the "twisting up" approximation. The underlying nonprecessing model, IMRPhenomT, is calibrated to the new release of numerical relativity simulations of the SXS Collaboration and its accuracy is comparable to the state-of-the-art nonprecessing dominant mode models as IMRPhenomX and SEOBNRv4. The precessing extension allows for flexibility choosing the Euler angles of the time-dependent rotation between the coprecessing and the inertial reference systems, including the single spin next-to-next-to-leading order and the double spin multiscale analysis post-Newtonian descriptions present in other models, numerical integration of the orbit averaged spin evolution equations, different choices for the evolution of the orbital angular momentum norm, and a simple approximation to the ringdown behavior.
