LIGO/Virgo S190930s: Coverage and upper limits from MAXI/GSC observations
Abstract
We examined MAXI/GSC all-sky X-ray images (2-20 keV) after the LVC trigger S190930s at 2019-09-30 13:35:41.246 UTC (GCN 25871). At the trigger time of S190930s, the high-voltage of MAXI/GSC was on, but the FOV was out of the 90% credible region of the bayestar skymap. 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 14:25:05 to 15:03:54 UTC (T0+2964 to T0+5293 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.
