Mereghetti (INAF IASF-Milano, Italy)\n\non behalf of the INTEGRAL multi-messenger collaboration:\nhttps://www.astro.unige.ch/cdci/integral-multimessenger-collaboration\n\nWe investigated serendipitous INTEGRAL observations carried out at the\ntime of the LIGO/Virgo burst candidate S190425z.  The satellite was\ncovering the entire localization region of the LIGO-Virgo event with a sensitivity depending on the source position.\nThe best sensitivity depends on the source location.\n\nWe investigated the SPI-ACS and IBIS/PICsIT light curves between -30 and +30 s from\nthe trigger time (2019-04-25T08:18:05 UTC, T0) on temporal scales from\n0.1 to 10s.\n\nIn the SPI-ACS or IBIS/PICsIT data, we do not detect a significant signal.\nIn SPI-ACS data, a marginally significant excess with S/N of 3.7 at is seen at T0+6s at the timescale of 1s.\nFurther analysis is ongoing, and will be reported in the coming circulars.\n\nhttps://www.astro.unige.ch/cdci/integral/transients/lvc-s190425z",
