Grand Park Otaru Hotel), Otaru, Hokkaido Japan, We 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., 著者人数: 15人, Meeting sponsors: The University of Tokyo, The Institute of Physical and Chemical Research, The Japan Society for the Promotion of Science, Number of authors: 15, 資料番号: AA0064574007, レポート番号: JAXA-SP-09-008E}, pages = {26--27}, publisher = {宇宙航空研究開発機構, Japan Aerospace Exploration Agency (JAXA)}, title = {Suzaku/WAM and Swift/BAT Joint Spectral Studies of Gamma-ray Bursts}, volume = {JAXA-SP-09-008E}, year = {2010} }
