Description Swift observations of the early X-ray afterglows of gamma ray bursts (GRBs)have revealed unexpected behaviors. One of the most puzzling features is the so called "plateau", the early afterglow phase where the lightcurve shows an unpredicted shallow decay. The long known spectral stability of the plateau emission has strongly favored interpretations based on prolonged energy injection in the emitting shock. However, recent findings suggest that, at least in some plateaus, the emission energy spectrum might come from the sum of two, temporal varying components. We propose a rapid ToO program (< 10 hours) with XMM-Newton EPIC to perform high quality time resolved spectral study of an X-ray afterglow during the plateau phase.

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.
