Abstract

Launched in April 1996, operational for six years, BeppoSAX has opened a new view on the X-ray universe, with its broad-band and wide angle instruments associated with flexible ground segment operations. In this paper we recall some of the history behind the development of the project, summarize some of its scientific achievements and comment on its heritage. [Copyright &y& Elsevier]

Abstract

Abstract: The error box of GRB980425 has been observed by XMM-Newton in March 2002, with the aim of measuring the late epoch X-ray emission of the supernova 1998bw and of clarifying its supposed association with the GRB itself. We present here the preliminary results obtained with the EPIC PN camera. Our observations confirm the association between SN 1998bw and GRB980425. The EPIC PN measurement of the SN 1998bw flux is significantly below the extrapolation of the power-law temporal trend fitted to the BeppoSAX points and implies a faster temporal decay. We propose different physical interpretations of the SN X-ray light curve, according to whether it is produced by one or more radiation components. [Copyright &y& Elsevier]
