Search for gamma-ray counterparts to FRBs in Konus-Wind data

We report preliminary results of the search in the Konus-Wind experiment data for hard X-ray/soft γ-ray emission in coincidence with publicly reported fast radio bursts (FRBs). We find no significant associations for any of the 581 FRBs in our sample and report upper limits to the high-energy fluence/peak flux for three spectral shapes, which generally describe short GRB, long GRB and magnetar giant flare spectra. In addition to study each individual FRB, we perform a stacking analysis of the bursts from each repeating source in our sample and a separate stacking analysis of the bursts from the non-repeating FRBs. We find no statistically significant excess of the cumulative emission over background level for either case.
