Angular-Momentum Loss and Radiated Lorentz Charge in Kerr Scattering at Quadratic Spin

We present a complete derivation of the radiated Lorentz charge in the scattering of two Kerr black holes at third post-Minkowskian order and quadratic spin. Starting from the leading Kerr waveform, reverse unitarity gives the connected finite-frequency contribution. It includes...
