Description
Inferring astrophysical and cosmological information from gravitational-wave observations from merging black holes and neutron stars relies on accurate predictions for the two-body dynamics and gravitational radiation. To avoid wrong scientific statements due to systematics in waveform models, upcoming observational runs with existing facilities, and with future detectors on the ground and in space, will require ever more accurate and precise waveform models, which include all physical effects. I will describe what it takes to build faithful waveform models for the entire coalescence combining different analytical methods with numerical relativity, and how perturbative results from scattering-amplitude and effective-field theory techniques could be employed to improve them, helping to achieve the stringent accuracy requirements.
