LIGO/Virgo G270580: MAXI/GSC observations
Abstract
We examined the MAXI/GSC all-sky X-ray images (2-20 keV) obtained in the orbit and the day after the LVC trigger G270580 at 2017-01-20 12:30:59.350 UTC (GCN 20486). In the 92-min orbit, MAXI/GSC scanned 66.7% of the whole sky, which includes 78.5% of the 90% regions in the LIB skymap. One day image covers 96.6% of the 90% regions in the LIB skymap. No significant new source was found in these images. The upper limits for the X-ray flux are different depending on the part of the sky. For instance, typical 2-20 keV 1-sigma (3-sigma) upper limits obtained from the one-orbit and oneday images are 13 (40) mCrab and 5 (16) mCrab, respectively.
