Prompt Emission Properties of X-ray Flashes and Gamma-ray Bursts

摘要：

I summarize the prompt spectral characteristics of X-ray flashes (XRFs) using the available spectral parameters of theBATSE, the BeppoSAX, the HETE-2, and the Swift gamma-ray bursts (GRBs). The spectral properties of XRFs are similarto those of classical GRBs (C-GRBs) except the Epeak energy and the fluence of XRFs are much smaller. The fluence ratiodistribution from XRFs to C-GRBs forms a continuum. This systematic study of the spectral properties of XRFs and C-GRBstightens an evidence that these bursts arise from the same phenomenon.
