AbstractWe report on results from joint spectral studies using 96 gamma-ray bursts (GRBs) which were simultaneously detected with the Suzaku/WAM and Swift/BAT. This sample contains 5 short GRBs and 36 GRBs with a wide range of known redshifts (z=0.089 to 6.3). For most of these bursts, Suzaku/WAM or Swift/BAT cannot determine the peak energy of the nu F(sub nu) spectrum (E(sub peak)) solely, but a combination of Suzaku/WAM and Swift/BAT could determine the E(sub peak) for 80 % of all the sample, owing to their broad band coverage of 15-5000 keV. The derived E(sub peak) concentrated on around 250 keV, although the distribution is slightly broader than the CGRO/BATSE distribution. We also verified the peak energy - isotropic radiation energy (E(sub peak)-E(sub iso)) relation for long GRBs including the high redshift GRB 050904 (z=6.3). One exception is the sub-luminous nearby GRB 060505. All the 5 short GRBs are outliers for this relation, suggesting that the radiation mechanisms are difference in short and long duration GRBs.
