AGILE Observations of Fast Radio Bursts

We report on a systematic search for hard X-ray and gamma-ray emission in coincidence with fast radio bursts (FRBs) observed by the AGILE satellite. used 13 years of archival data searching time coincidences between exposed FRBs events detectable MCAL (0.4-100 MeV) GRID (50 MeV-30 GeV) detectors at timescales ranging from milliseconds to days/weeks. The current sky coverage allowed us extend high-energy preceding following FRB occurrence. considered all sources currently included catalogues, identified sub-sample (15 events) which good exposure either or was obtained. In this paper we focus non-repeating FRBs, compared few nearby repeating sources. did not detect significant MeV GeV any event. Our upper limits (ULs) energy range were obtained sub-millisecond seconds, minutes weeks around event times. sub-set 5 2 whose distances are most likely smaller than that 180916.J0158+65 (150 Mpc). For these sources, our ULs translate into isotropically-emitted about 3x10^46 erg, comparable 2004 giant flare Galactic magnetar SGR 1806-20. On average, emit pulses energies significantly larger recently detected 1935+2154 yet associated intense flaring.
