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.
