The detection of GW230529 indicated that black hole–neutron star mergers are promising candidates for multi-messenger observations due to the presence of a low-mass black hole. Joint observations of gravitational and electromagnetic waves from these mergers provide unique opportunities to constrain the equation of state of neutron stars and to investigate the contribution of these events to the abundances of heavy elements via r-process nucleosynthesis. Numerical relativity simulations are the only tool able to create a bridge between theory and observations. In this talk, we present state-of-the-art simulation results, examining the impact of the neutron star equation of state, black hole spin and the mass ratio on gravitational wave signatures and ejecta properties. We also discuss the distinguishability of these effects with current and next-generation gravitational wave detectors.
