LVC S190425z
We investigated serendipitous INTEGRAL observations carried out at the
time of the LIGO/Virgo burst candidate S190425z. The satellite was
covering the entire probability of the LIGO-Virgo
localization.
The best sensitivity depends on the source location.
We investigated the SPI-ACS and IBIS/PICsIT light curves between -30 and +30 s from
the trigger time (2019-04-25T08:18:05 UTC, T0) on temporal scales from
0.1 to 10s.
In the SPI-ACS or IBIS/PICsIT data, we do not detect a significant signal.
In SPI-ACS data, a marginally significant excess with S/N of 3.6 at is seen at T0+6 s at a timescale of 1s.
Further analysis is ongoing, and will be reported in the coming circulars
