Abstract
We report on the search results of Fast Radio Bursts (FRBs) from three Gamma- ray Bursts (GRBs) at 2256 MHz using the 40-m radio telescope located at the YunNan Astronomical Observatory (YNAO). The search for signals was triggered by the Burst Alert Telescope (BAT) on- board the Swift satellite. Radio single pulses are searched in the data over a large range of dispersion measure from 0 to 5000 pc/cm3 in step of 50 pc/cm3. No FRB-like emission from the prompt phase of GRBs are detected with significance > 5?. If there are FRBs related to the GRBs, we set an upper limit on the ux density of radio pulses of 2.5 Jy for GRB140512A and 8.0 Jy for GRBs 140629A and 140703A with the sensitivity of the telescope. A statistical analysis of the GRB data reveals that the events detected above 5? are consistent with the thermal noise uctuations.
