Abstract
We present a study of NGC 4993, the host galaxy of the GW170817 gravitational
wave event, the GRB170817A short gamma-ray burst (sGRB) and the AT2017gfo
kilonova. We use Dark Energy Camera imaging, AAT spectra and publicly available
data, relating our findings to binary neutron star (BNS) formation scenarios
and merger delay timescales. NGC4993 is a nearby (40 Mpc) early-type galaxy,
