We report on the prompt and afterglow emission observations of the dark burst GRB010214 with BeppoSAX .T he prompt emission shows possible evidence of variable absorption from NH = 3:0 +5:1 2:0 10 23 cm 2 in the first 6 s of the event to a value consistent with the Galactic column density (N G = 2:66 10 20 cm 2 ) in the GRB direction. An X-ray afterglow emission in the 2-10 keV energy band was detected with BeppoSAX, but an analogue search at lower wavelengths (optical, IR and radio) was… Expand

We report observation results of the prompt X- and gamma-ray emission from GRB 000528. This event was detected with the Gamma-Ray Burst Monitor and one of the two Wide Field Cameras aboard theExpand
Multiwavelength study of the very long GRB 020410
GRB 020410 is by far the longest γ-ray burst (with a duration of about 1600 s) to have been followed up from the X-ray through the radio regime. Afterglow emission was detected in X-rays and atExpand
The BeppoSAX catalog of GRB X-ray afterglow observations
We present the catalog of X-ray afterglow observed by BeppoSAX from the launch of the satellite to the end of the mission. Thirty-three X-ray afterglows out of 39 observations were securelyExpand
Comparative study of the two large flares from SGR1900+14 with the BeppoSAX Gamma-Ray Burst Monitor
We report on spectral and temporal results of the 40-700 keV observations, obtained with the Gamma-Ray Burst Monitor (GRBM) on board BeppoSAX, of the two large flares from the Soft Gamma-ray RepeaterExpand
We present here a comprehensive study of the optical/near-infrared (IR) upper limits for gamma-ray bursts that have an X-ray afterglow. We have extrapolated the X-ray afterglows to opticalExpand
Gamma‐ray burst optical follow ups with robotic telescopes
Gamma-ray bursts (GRBs) are the most energetic phenomenon in the universe, emitting their energy throughout the electromagnetic spectrum. Due to their initial brightness and highly transient nature,Expand
The FWHM of local pulses and the corresponding power-law index of gamma-ray burst FRED pulses
The FWHM of gamma-ray burst (GRB) pulses is known to be related to energy by a power law. We wonder if the power-law index a is related to the corresponding local pulse width FWHM0. Seven FRED (fastExpand
