|Title||Disclosing the gamma-ray burst circumburst ambient with XMM-Newton|
|Author||Dr Sergio Campana|
|Description||Long GRBs signal the death of massive stars. Their afterglow emission can be used to probe the progenitor ambient through a detailed study of the absorption pattern. This is done at optical wavelengths with impressive results. Detailed studies of the absorption pattern imprinted in the X ray spectrum by the circumburst material can be carried out, allowing us to shed light on the material metallicity, composition and distance of the absorber. We propose to continue observing bright Swift GRBs within 9 hr to derive with higher significance an unbiased characterization of the circumburst material. For very bright GRBs we can also search for WHIM features using the GRB as a lighthouse.|

|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.
