Abstract: Gravitational waves from binary neutron star mergers offer us a clean way of probing dense matter physics that is difficult to access from ground-based nuclear experiments. In this talk, I first review the current status of implications on nuclear physics after the recent event GW170817. Next, I will review approximate universal relations among certain neutron star global quantities (like tidal deformabilities) that are insensitive to the underlying equation of state. I will then explain how such relations can be used to probe dense matter physics with gravitational wave observations, and how the universality of these relations has improved after GW170817. I will end by describing how one can coherently stack post-merger signals via universal relations to probe nuclear physics with future observations.
