Search for Gamma Ray Transient Activity with the HAWC Observatory at the locations of Fast Radio Bursts

Over the past few years the number of known fast radio bursts (FRBs) has grown rapidly, yet we still don't have a clear picture of the progenitors of these events. Multiwavelength follow up of these transients will help constrain the available models for FRBs, and the HAWC Gamma-Ray Observatory has data covering a large number of FRBs. The HAWC data set contains contemporaneous observations of over 200 FRB events which was searched for short time scale gamma-ray emission. For each FRB, a time window of 100s before to 500s after the reported time were searched for bursts of 1 s, 5 s and 10 s duration. We then perform a simulation of the background at that location and distance over the same duration, and the two resulting distributions are compared to see the probability of a gamma-ray excess on any time window surrounding the FRB. The limits placed on the short timescale gamma-ray emission is also used to set an energy ratio of TeV gamma ray to radio detection which can be used to constrain models used to explain FRBs.
