Abstract:
Over the past two years, numerical simulations have accessed the merger phase of binary black hole coalescences for the first time, beginning to unveil the physics of the transition between the inspiraling system and the final distorted black hole. In this talk, I will present a study of this regime based on the evolution of a massless scalar field on a set of fixed backgrounds, each provided by a spatial hypersurface generated numerically during the merger.
