LIGO/Virgo/KAGRA S240422ed: 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 S240422ed at 2024-04-22 21:35:13.417 UTC (GCN #36236). At the trigger time of S240422ed, the high-voltage of MAXI/GSC was off, and it was turned on at T0+620 sec (+10.3 min). The first one-orbit (92 min) scan observation with GSC after the event covered 100% of the 90% credible region of the bayestar skymap from 22:32:11 to 22:37:06 UTC (T0+3418 to T0+3713 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.
