Time-evolution of Peak Energy and Luminosity Relation within Pulses for GRB 061007: Probing Fireball Dynamics
Masanori Ohno, Kunihito Ioka, Kazutaka Yamaoka +3
We perform a time-resolved spectral analysis of bright, long Gamma-ray burst GRB 061007 using Suzaku/WAM and Swift/BAT. Thanks to the large effective area of the WAM, we can invest…
Intrinsic properties of a complete sample of HETE-2 gamma-ray bursts. A measure of the GRB rate in the Local Universe
A. Pélangeon, J. -L. Atteia, Y. E. Nakagawa +32
Aims: Taking advantage of the forthcoming Catalog of the HETE-2 mission, the aim of this paper is to evaluate the main properties of HETE-2 GRBs - the E_peak, the T_90 and the E_is…
Suzaku Observations of SGR 1900+14 and SGR 1806-20
Yujin E. Nakagawa, Tatehiro Mihara, Atsumasa Yoshida +8
Spectral and timing studies of Suzaku ToO observations of two SGRs, 1900+14 and 1806-20, are presented. The X-ray quiescent emission spectra were well fitted by a two blackbody fun…
The Swift Discovery of X-ray Afterglows Accompanying Short Bursts from SGR 1900+14
Y. E. Nakagawa, T. Sakamoto, G. Sato +3
The discovery of X-ray afterglows accompanying two short bursts from SGR 1900+14 is presented. The afterglow luminosities at the end of each observation are lower by 30-50% than th…
Status of GRB Observations with the Suzaku Wideband All-sky Monitor
M. S. Tashiro, Y. Terada, Y. Urata +28
The Wide-band All-sky Monitor (WAM) is a function of the large lateral BGO shield of the Hard X-ray Detector (HXD) onboard Suzaku. Its large geometrical area of 800 cm^2 per side,…
Multiple Component Analysis of Time Resolved Spectra of GRB041006: A Clue to the Nature of Underlying Soft Component of GRBs
Yuji Shirasaki, Atsumasa Yoshida, Nobuyuki Kawai +30
GRB 041006 was detected by HETE-2 at 12:18:08 UT on 06 October 2004. This GRB displays a soft X-ray emission, a precursor before the onset of the main event, and also a soft X-ray…
