A Unified Jet Model of X-Ray Flashes, X-ray Rich GRBs and GRBs
D. Q. Lamb, T. Q. Donaghy, C. Graziani
HETE-2 has provided strong evidence that the properties of X-Ray Flashes (XRFs) and GRBs form a continuum, and therefore that these two types of bursts are the same phenomenon. We…
Gamma-Ray Bursts as a Laboratory for the Study of Type Ic Supernovae
D. Q. Lamb, T. Q. Donaghy, C. Graziani
HETE-2 has confirmed the connection between GRBs and Type Ic supernovae. Thus we now know that the progenitors of long GRBs are massive stars. HETE-2 has also provided strong evide…
Astrometric Calibration and Estimate of the Systematic Error in WXM Localizations Obtained by the Chicago Bayesian Method
C. Graziani, Y. Shirasaki, T. Donaghy +11
WXM gives GRB localizations in instrument coordinates. WXM localizations must be converted to celestial coordinates using spacecraft aspect information obtained by the optical came…
GRB010921: Localization and Observations by the HETE Satellite
G. Ricker, K. Hurley, D. Lamb +36
On September 21 at 18950.56 SOD (05:15:50.56) UT the FREGATE gamma-ray instrument on the High Energy Transient Explorer (HETE) detected a bright gamma-ray burst (GRB). The burst wa…
