LIGO/Virgo/KAGRA S231113bw: Coverage and upper limits from MAXI/GSC observations
Abstract
We examined MAXI/GSC all-sky X-ray images (2-20 keV) after compact binary merger candidate S231113bw at 2023-11-13 20:04:17 UTC (GCN 35016). At the trigger time of S231113bw, the high-voltage of MAXI/GSC was off, and it was turned on at T0+285 sec (+4.8 min). The first one-orbit (92 min) scan observation with GSC after the event covered 53% of the 90% credible region of the bayestar skymap from 20:09:15 to 21:34:10 UTC (T0+298 to T0+5393 sec). No significant new source was found in the region in the one-orbit scan observation. A typical 1-sigma averaged upper limit obtained in one scan observation is 20 mCrab at 2-20 keV. If you require information about X-ray flux by MAXI/GSC at specific coordinates, please contact the submitter of this circular by email.
