Hyperbolic encounters of binary black holes in scalar Gauss-Bonnet gravity

In this talk, I will present results of simulations of hyperbolic encounters of equal-mass, non-spinning black holes sourcing the scalar field in scalar Gauss-Bonnet gravity. Working at the decoupling limit, the background spacetime represents the evolution of black hole binaries in General Relativity. Depending on the impact parameter, the black holes scatter, merge or exhibit zoom-whirl orbits. I will also discuss the evolution of the Gauss-Bonnet scalar field determined by the different binary evolutions in the background and present the scalar energy flux.
