Searching for Short GRBs in Soft Gamma-Rays with INTEGRAL/PICsIT

The first electromagnetic detections associated with a gravitational wave trigger on 17 August 2017 produced a flurry of results across the EM spectrum. A notable example at hard X-ray/soft gamma-ray energies is how extremely under luminous the short gamma-ray burst (SGRB) was compared to others with known redshifts, which suggests a population of low luminosity events. The most popular interpretation has been that the GRB was viewed off-axis, rather than that the event had an intrinsically low luminosity. Regardless, this result has spurred searches for SGRBs below instrument trigger thresholds in hopes of finding similar bursts. Here we have analyzed data from the INTEGRAL soft gamma-ray detector IBIS/PICsIT ( 200 keV - 10 MeV) to try to corroborate the untriggered SGRB candidates reported by Fermi/GBM. In addition, we present initial results of our real-time burst analysis with PICsIT.
