The overarching problem that we wished to tackle was the identification of the most urgent improvements required to faithfully describe coalescences of non-circularized binary black holes (BBHs) (i.e. highly eccentric inspirals, hyperbolic scatterings and dynamical captures) within the EOB framework. In particular, we focused on:
- The inclusion of high order analytical information – coming from post-Newtonian and post-Minkowskian computations – within the EOB framework, and its impact on scattering angle computations;
- The modeling of the merger, ringdown and remnant BH born out of a highly eccentric coalescence;
- The improvement of the computational performance of EOB models for non-circularized systems via analytical and Machine learning techniques.
- The application of EOB-based models to gravitational wave data analysis.
