Black hole scattering near the transition to plunge: Self-force and resummation of post-Minkowskian theory

Oliver Long, Christopher Whittall, Leor Barack

Geodesic scattering of a test particle off a Schwarzschild black hole can be parameterized by the speed-at-infinity $v$ and the impact parameter $b$, with a "separatrix", $b=b_c(v)…
