At this conference, we will present a brief overview of the observational performance of Swift Ultra-violet/optical Telescope (UVOT) in response to the Gravitational Wave (GW) alerts announced by the Advanced Laser Interferometer Gravitational Wave Observatory and the Advanced Virgo detector during the O3 period. We will also report on 40 serendipitous sources followed up with Swift/UVOT; of these 28 were discovered by UVOT. Compared to archival u or g-band catalogued values, the 28 UVOT detected sources changed in magnitude at the 3 sigma level. We examine the properties of these sources and investigate their nature. Finally, we discuss the importance of UVOT in the search of the electromagnetic counterparts of GW events and improvements that can be made in the run-up to O4.
All attendees are expected to show respect and courtesy to other attendees and staff, and to adhere to the NAM Code of Conduct.
