...and 4 moreThe INTEGRAL observatory performed follow-up observations of the LIGO/Virgo compact binary merger candidate S190408an (GCN #24069) in the form of the fast TOO operational test. The observations were carried out from 2019-04-10 11:13:07 to 2019-04-10 17:10:47 in the staring and hexagonal dithering modes with a total observing time of approximately 18 ks.
They were centred on the coordinates RA=350.2, Dec=-56.0 and covered ~42% of the LIGO/Virgo localization probability with the highest sensitivity. We do not detect any new sources in the complete IBIS/ISGRI (25-60 keV) mosaicked image with the best sensitivity of 16.5 mCrab (1.6e-10 erg/cm2/s, 3-sigma upper level) in this energy range.
