Intrinsic spectra and energetics of BeppoSAX Gamma-Ray Bursts with known redshifts
We present the main results of a study of spectral and energetics properties of twelve gamma-ray bursts (GRBs) with redshift estimates. All GRBs in our sample were detected by BeppoSAX in a broad…
Spectral constraints on the redshift of the optical counterpart to the γ-ray burst of 8 May 1997
Brief, intense bursts of γ-rays occur approximately daily from random directions in space, but their origin has remained unknown since their initial detection almost 25 years ago. Arguments based on…
The high energy instrument PDS on-board the BeppoSAX X{ray astronomy satellite
BeppoSAX/PDS experiment is one of four narrow eld instruments of the BeppoSAX payload, that also includes two wide eld cameras. The goal of PDS is to extend the energy range of BeppoSAX to hard…
JEM-X: The X-ray monitor aboard INTEGRAL ?
The JEM-X monitor provides X-ray spectra and imaging with arcminute angular resolution in the 3 to 35 keV band. The good angular resolution and the low energy response of JEM-X plays an important…
Observation of contemporaneous optical radiation from a γ-ray burst
The origin of γ-ray bursts (GRBs) has been enigmatic since their discovery. The situation improved dramatically in 1997, when the rapid availability of precise coordinates, for the bursts allowed the…
An unusual supernova in the error box of the γ-ray burst of 25 April 1998
The discovery of afterglows associated with γ-ray bursts at X-ray, optical and radio wavelengths and the measurement of the redshifts of some of these events, has established that γ-ray bursts lie at…
Identification of a host galaxy at redshift z = 3.42 for the γ-ray burst of 14 December 1997
Knowledge of the properties of γ-ray bursts has increased substantially following recent detections of counterparts at X-ray, optical and radio wavelengths. But the nature of the underlying physical…
Discovery of an X-ray afterglow associated with the γ-ray burst of 28 February 1997
Establishing the nature of γ-ray bursts is one of the greatest challenges in high-energy astrophysics. The distribution of these bursts is isotropic across the sky, but inhomogeneous in space, with a…
A hypernova model for the supernova associated with the γ-ray burst of 25 April 1998
The discovery of the unusual supernova SN1998bw, and its possible association with the γ-ray burst GRB 980425, provide new insights into the explosion mechanism of very massive stars and the origin…
Gamma Ray Bursts in the Afterglow Era
In this review paper I will summarize some of the relevant results obtained with the Italian satellite BeppoSAX on the prompt and afterglow emission of Gamma Ray Bursts. I will also discuss the most…
