We found a clear proportional correlation between hard/soft lags and widths of spikes for long GRBs, which is smoothly connected with those of short GRBs. We next performed spike-resolved spectral analysis of 63 spikes for 12 long GRBs with known redshifts, using Suzaku-WAM, Swift-BAT, and HETE-2 data. We found a clear correlation between the intrinsic peak energy (E(sub p)) and the isotropic radiated luminosity (L(sub iso)) for individual spikes, E(sub p) is propotional to L(sub iso)(exp 1/2) , over four orders of magnitude of luminosity. Remarkably, E(sub p) and L(sub iso) in 6 short GRBs with known redshifts were also within statistical errors of the relation for long GRBs.

内容記述 | We report on a detailed comparison between short GRBs and spikes of long GRBs in timing and spectral properties using bright GRBs observed by Suzaku-WAM. We first performed spectral time lag analysis of 217 spikes in 102 bright GRBs. We found a clear proportional correlation between hard/soft lags and widths of spikes for long GRBs, which is smoothly connected with those of short GRBs. We next performed spike-resolved spectral analysis of 63 spikes for 12 long GRBs with known redshifts, using Suzaku-WAM, Swift-BAT, and HETE-2 data. We found a clear correlation between the intrinsic peak energy (E(sub p)) and the isotropic radiated luminosity (L(sub iso)) for individual spikes, E(sub p) is propotional to L(sub iso)(exp 1/2) , over four orders of magnitude of luminosity. Remarkably, E(sub p) and L(sub iso) in 6 short GRBs with known redshifts were also within statistical errors of the relation for long GRBs. From these two results, we conclude that, in our sample, there is no clear differences between short GRBs and spikes of long GRBs in the time lag and the E(sub p)- L(sub iso) relation. | |||||
