Their kinematics –positions, velocities, and trajectories within the host galaxy– encode the outcomes of two supernovae and the binary interactions that preceded them. By analyzing these motions, we can inform stellar models, formation channels, and binary survival rates. BNSs are also key progenitors of gravitational-wave events and a prime location of nucleosynthesis. Understanding their merger locations improves merger rate predictions, spatial localisation for gravitational-wave and electromagnetic counterparts, and our understanding of cosmic chemical enrichment. As BNS datasets grow and gravitational-wave observations become increasingly available, a comprehensive understanding of BNS kinematics becomes essential for interpreting the observed populations. This thesis addresses that need by focusing on the motion and merger locations of BNSs within their host galaxies, delivering a general theoretical framework for the motion of kicked objects in the Galactic potential, a comprehensive kinematical characterisation of the observed BNS in the Milky Way, and a predictive framework that connects BNS kinematics to the observed merger locations in external galaxies.","Radboud University, 01 december 2025","Promotores : Levan, A.J., Nelemans, G.A.
