Description
Recently there has been considerable progress in using amplitude-based techniques to extract gravitational waves templates produced by the coalescence of strongly gravitating compact objects such as black holes and neutron stars. In this talk I will show how to construct a new minimally coupled Yang Mills Lagrangian based on the introduction of a new covariant derivative that incorporates classical spin effects. Using double copy techniques we use this theory to extract gravity amplitudes and observables up to 2PM that are relevant to describe Kerr binary dynamics to all orders in the spin. If time permits, I will talk about 3PM radiation-reaction effects and radiative observables in the case of Kerr black-holes scattering, whose description naturally fits in the above-mentioned theories.
