Description
In recent years, the gravitational wave community has seen growing
interest in modelling scattering events between 2 black holes (BH) since such
events serve to better probe regions of strong gravity close to the primary BH.
While some progress on this has been made using the post-Minkowskian
approximation using techniques from effective field theory and scattering
amplitudes, a complimentary approach is to use the Gravitational Self Force (GSF)
which is more suited to analysing motion in the strong field. In this talk, I describe
how these events can be modelled for self-force applications using a numerical
scheme based on hyperboloidal slices that are comoving with the smaller particle.
Furthermore, I will show how this scheme circumvents the divergences that
plagued earlier time-domain implementations.
