Evidence for dynamically driven formation of the GW170817 neutron star binary in NGC 4993

Evidence for dynamically driven formation of the GW170817 neutron star binary in NGC 4993

We present a study of NGC 4993, the host galaxy of the GW170817 gravitational-wave event, the GRB 170817A short gamma-ray burst (sGRB), and the AT 2017gfo kilonova. We use Dark Energy Camera imaging, AAT spectra, and publicly available data, relating our findings to binary neutron star (BNS) formati...
