Spinning waveforms in cubic effective field theories of gravity
Andreas Brandhuber, Graham R. Brown, Gang Chen +2
We derive analytic all-order-in-spin expressions for the leading-order time-domain waveforms generated in the scattering of two Kerr black holes with arbitrary masses and spin vect…

Systematic integral evaluation for spin-resummed binary dynamics
Gang Chen, Jung-Wook Kim, Tianheng Wang
Computation of spin-resummed observables in post-Minkowskian dynamics typically involve evaluation of Feynman integrals deformed by an exponential factor, where the exponent is a l…

Dynamics of Spinning Binary at 2PM
Gang Chen, Tianheng Wang
We consider the covariant proposal for the gravitational Compton amplitude for a Kerr black hole. Employing the covariant three- and four-point Compton amplitudes, we assemble the…
