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…
HETE-2 Localizations and Observations of Four Short Gamma-Ray Bursts: GRBs 010326B, 040802, 051211 and 060121
T. Q. Donaghy, D. Q. Lamb, T. Sakamoto +34
Here we report the localizations and properties of four short-duration GRBs localized by the High Energy Transient Explorer 2 satellite (HETE-2): GRBs 010326B, 040802, 051211 and 0…
HETE-2 Observation of two gamma-ray bursts at z > 3
J. -L. Atteia, N. Kawai, R. Vanderspek +36
GRB 020124 and GRB 030323 constitute half the sample of gamma-ray bursts with a measured redshift greater than 3. This paper presents the temporal and spectral properties of these…
Global Characteristics of X-Ray Flashes and X-Ray-Rich GRBs Observed by HETE-2
T. Sakamoto, D. Q. Lamb, C. Graziani +35
We describe and discuss the global properties of 45 gamma-ray bursts (GRBs) observed by HETE-2 during the first three years of its mission, focusing on the properties of X-Ray Flas…
High Energy Observations of XRF 030723: Evidence for an Off-axis Gamma-Ray Burst?
N. R. Butler, T. Sakamoto, M. Suzuki +34
We report High Energy Transient Explorer 2 (HETE-2) Wide Field X-ray Monitor/French Gamma Telescope observations of XRF030723 along with observations of the XRF afterglow made usin…
HETE Observations of the Gamma-Ray Burst GRB030329: Evidence for an Underlying Soft X-ray Component
R. Vanderspek, T. Sakamoto, C. Barraud +30
An exceptionally intense gamma-ray burst, GRB030329, was detected and localized by the instruments on board the High Energy Transient Explorer satellite (HETE) at 11:37:14 UT on 29…
