GLOBAL CHARACTERISTICS OF X-RAY FLASHES AND X-RAY-RICH GAMMA-RAY BURSTS OBSERVED BY HETE-2
We describe and discuss the global properties of 45 gamma-ray bursts (GRBs) observed by HETE-2 during the first 3 years of its mission, focusing on the properties of X-ray flashes (XRFs) andExpand

A Comprehensive Study of Short Bursts from SGR1806$-$20 and SGR1900$+$14 Detected by HETE-2
Temporal and spectral studies of short bursts (? a few hundred milliseconds) are presented for the soft gamma repeaters (SGRs) 1806-20 and 1900+14 using the HETE-2 samples. In five years from 2001 toExpand

Spectral-Lag Relations in GRB Pulses Detected with HETE-2
Using a pulse-fit method, we investigated the spectral lags between the traditional gamma-ray band (50–400 keV) and the X-ray band (6–25 keV) for 8 GRBs with known redshifts (GRB 010921, GRB 020124,Expand
