Description
The study of unbound binary-black-hole encounters provides a gauge-invariant approach to exploring strong-field gravitational interactions in two-body systems, which can subsequently inform waveform models for bound orbits. In this talk, we compare our NR scattering angle results from the Spectral Einstein Code (SpEC) to the post-Minkowskian PM-based effective-one-body (EOB) closed-form models SEOB-PM and wEOB and the post-Newtonian-based EOB evolution models SEOBNRv5 and TEOBResumS-Dalí.
