Boundary to bound dictionary for generic Kerr orbits
read the original abstract
We establish a new relation between classical observables for scattering and bound orbits of a massive probe particle in a Kerr background. We find an exact representation of the Hamilton-Jacobi action in terms of the conserved charges which admits an analytic continuation, both for the radial and polar contribution, for a general class of geodesics beyond the equatorial case. Remarkably, this allows to extend the boundary to bound dictionary and it provides an efficient method to compute the deflection angles and the time delay for scattering orbits, as well as frequency ratios for bound orbits, in the probe limit but at all orders in the perturbative expansion.

Binary black hole scattering with generic spins
First NR-PM comparison for generic-spin black hole scattering reveals strong-field precessional turning-point structure with polar-angle sign change absent from perturbative PM.

The radial action for massive particles in spherically symmetric geometries: Exact resummation at any PM order
The massive-particle radial action and scattering angle in Schwarzschild, Schwarzschild-Tangherlini and D3-brane geometries are resummed in hypergeometric/Fox-Wright form, and the massive scalar quantum a-cycle is ide...

Resummed energy loss in extreme-mass-ratio scattering using critical orbits
Near-separatrix logarithmic divergence, anchored by fitted unstable-circular-orbit fluxes, yields resummed formulas for energy loss in extreme-mass-ratio scattering that track exact numerical calculations to about 10-25%.

Unexpected Symmetries of Kerr Black Hole Scattering
The work establishes conservation of several quantities in Kerr black hole scattering and presents evidence that a spinning probe satisfies asymptotic integrability to quartic spin order at all post-Minkowskian orders.
