    Abstract

    The X-ray/gamma-ray mission INTEGRAL detected the short GRB170817A and demonstrated its association to a gravitational wave trigger, GW170817. This marks the first time a binary neutron star merger was detected by the LIGO-Virgo collaboration and that an electromagnetic counterpart to a gravitational wave event has been observed. GRB170817A was detected by the SPI-ACS on-board INTEGRAL and the Fermi/GBM instruments ∼ 1:7 s after the GW event. Following the prompt emission, INTEGRAL performed pointed observations for 5.4 days. During this time the instruments provided stringent upper limits on any electromagnetic signal in the 3keV to 8 MeV range. Interestingly, the GRB was found to be extremely subluminous.In light of these results from GRB170817A, we have begun analysis of soft gamma-ray data(200 keV - 2:6 MeV ) from INTEGRAL/PICsIT. With this wide field-of-view instrument, we have begun searching for untriggered SGRBs reported by Fermi/GBM as well as preparing for real-time analysis during future LIGO-Virgo observing runs.
