We report the results of the rapid follow-up observations of gamma-ray bursts ( GRBs ) detected by the Fermi satellite to search for associated fast radio bursts .
The observations were conducted with the Australian Square Kilometre Array Pathfinder at frequencies from 1.2–1.4 GHz .
A set of 20 bursts , of which four were short GRBs , were followed up with a typical latency of about one minute , for a duration of up to 11 hours after the burst .
The data was searched using 4096 dispersion measure trials up to a maximum dispersion measure of 3763 pc cm ^ { -3 } , and for pulse widths w over a range of duration from 1.256 to 40.48 ms. No associated pulsed radio emission was observed above 26 { Jy ms } ( w / 1 { ms } ) ^ { -1 / 2 } for any of the 20 GRBs .
