Title The Unique Case of the Supernova-GRB Event of 25 April 1998

Description BSAX and BATSE-XTE were able to localize about 20 Gamma Ray Bursts (GRBs).For 13 of these X-ray afterglows have been detected. The observed X-ray counterparts generally fade rapidly and monotonically with time, following a power-law with an average index of 1.3. The only exception is GRB980425. This event is positio- nally and temporally consistent with the Type Ic supernova SN 1998bw exploded in the nearby galaxy ESO 184-G82 (z=0.0085). This has raised the hypothesis that a class of GRBs are produced by supernovae. Two weak sources were discovered in the X-ray error circle by the follow-up BSAX observations but neither of the two follows the classical power-law afterglow behavior. The aim of the proposed XMM observ. is to study the spatial and spectral properties of these two sources.

Mission Description The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations.
Since Earth's atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis.
