Discovery of an X-ray afterglow associated with the gamma-ray burst of 28 February 1997
Article Abstract:
An X-ray afterglow was discovered by the Beppo-SAX satellite following the gamma-ray burst on Feb 28 1997. A substantial proportion of the gamma-ray burst's total energy was contained in the X-ray transient. A multi-wavelength observational campaign was inititated by the quick detection of the gamma-ray burst that led to the discovery of a fading optical transient. The Beppo-SAX measurement explains the link between the location capability of radio, optical and X-ray astronomy and the gamma-ray phenomenology.

The energetic afterglow of the gamma-ray burst of 14 December 1997
Article Abstract:
Infrared observations of the fading optical transient connected with the gamma-ray burst of Dec 14, 1997, known as GRB971214, aimed mainly to infer fundamental parameters of the burst. Observations were carried out in the near-infrared band and at radio wavelengths. The models used in this research indicate that the afterglow emission arises from non-radiative shocks. The afterglow emission is similar in nature to the emission from supernovae. However, it is more energetic by two orders of magnitude.
