Some #Swift15Science to wrap up our 15th 'birthday' - the association between short-duration gamma-ray bursts and binary neutron star mergers. This was a decade+ effort leading up to the multi-messenger era - let's walk through some of the key results ...

The first afterglow - and hence host galaxy - detection for a bona fide short GRB was from GRB050509B. The likely host galaxy - a massive elliptical - was unlike any of the star-forming galaxies in which long GRBs occur ...

Over the next decade the accumulation of more afterglows strongly supported an older progenitor system, and the locations of these afterglows *within* their host galaxies were consistent with predictions for binary neutron star mergers (figure from Fong et al. 2013) ...
