Searching For Fast Radio Burst Counterparts with Swift's Burst Alert Telescope

Fast Radio Bursts (FRBs) are millisecond-long bursts of GHz-frequency emission [1-2] with Dispersion Measures large enough to be of a cosmological origin. There has yet to be a non-radio counterpart or high-confidence host galaxy detected for any FRB, leaving their true nature to be very mysterious. Using sub-threshold archival data from Swift's Burst Alert Telescope (BAT; [3]) we searched for evidence of a gamma-ray counterpart to any of the FRBs. In this talk I will present the details and results of our search. If real-time FRB alerts are integrated into the Astrophysical Multimessenger Observatory Network (AMON; [4]), sub-threshold FRBs can be detected through real-time spatial and temporal coincidences with other messengers. I will also talk about the real-time AMON analysis that's currently running. \newline [1] Lorimer, D.
