Abstract.
The BeppoSAX Wide Field Cameras have been successful in detecting gamma-ray bursts in the 2-26 keV energy range. While most detected bursts are also strong emitters at higher energies, a significant fraction have anomalously low gammaray flux. The nature of these “Fast X-ray Transients” (FXTs), and their relation to gamma-ray bursts (GRBs), is unknown. We use BATSE untriggered continuous data to examine the > 20 keV gamma-ray properties of the events detected in common with BeppoSAX. Temporaland spectralc haracteristics, such as peak flux, fluence, duration, and spectrum are compared to the full population of triggered BATSE GRBs. We find that FXTs have softer spectra than most triggered bursts, but that they are consistent with the extrapolated hardness expected for low-intensity GRBs.
