Abstract
We present the first unified model for the general relativistic dynamics and gravitational radiation of generic compact binaries. is a model based on the effective-one-body framework incorporating tidal interactions, generic spins, multipolar radiation reaction/waveform, and numerical relativity information. It allows the computation of gravitational waves and other dynamical gauge invariants from binaries (black holes, neutron stars, and neutron star–black hole binaries) evolving along orbits (quasicircular, eccentric, and nonplanar) through merger and including scattering. The performances of in the strong-field regime are showcased by comparisons with a large sample of 1395 high-accuracy numerical relativity simulations. allows the computation of faithful waveforms for gravitational wave astronomy, providing at the same time an understanding and a prediction of the strong-field dynamics.
