LIGO/Virgo G274296: DLT40 follow-up observation
Abstract
We report the observation of 25 galaxies within the LVC error region for the GW trigger G274296 using the cWB localization map.We selected 46 galaxies from the GWGC catalogue within 80.0% of the trigger error region, within a distance of 40.0 Mpc, brighter that -17.5 mag and at a Declination < 20 degree. 25 of those galaxies have been observed using the Prompt 5 telescope and are part of the ongoing DLT40 search. They represent the 1.3% of all galaxies within 40.0 Mpc in the Glade catalogue within the LVC error region for the GW trigger and contains 6.1% of all B band luminosity of those galaxies. We started to observe these sample of galaxies on 2017-2-17 and monitored them for 3 weeks after the GW trigger. No interesting transients have been identified down to a limit magnitude of 18.5.
