Abstract
On 14 August 2019, the LIGO and Virgo Collaborations alerted the astronomical community of a high significance detection of gravitational waves and classified the source as a neutron star - black hole (NSBH) merger, the first event of its kind. In search of an optical counterpart, the Dark Energy Survey (DES) Gravitational Wave Search and Discovery Team performed the most thorough and accurate analysis to date, targeting the entire 90 percent confidence level localization area with Blanco/DECam 0, 1, 2, 3, 6, and 16 nights after the merger was detected. Objects with varying brightness were detected by the DES Search and Discovery Pipeline and we systematically r...
