Description
I present the first numerical simulations of binary black holes and binary neutron star mergers in scalar–Gauss–Bonnet gravity performed in the modified puncture gauge, which is a well-motivated theory from an effective field theory point of view. Implemented within both GRChombo and MHDuet Numerical Relativity codes, our modified formulation enables stable evolution through merger and post-merger phases. These results open the door to systematic studies of scalar-Gauss-Bonnet effects on the gravitational wave signal and remnant dynamics in this class of modified gravity theories.
