|Title||Gamma-Ray bursts as probes to study interstellar dust, and vice versa|
|Author||Dr Andrea Tiengo|
|Description||We propose a ToO observation of a low Galactic latitude (|b| < 5 deg) and bright (15-150 keV fluence >2e-6 erg-cm2) GRB, with the main objective of studying the time variable halo that might be formed by dust scattering of the GRB X-ray emission. Thin rings are formed if a large quantity of dust is concentrated in discrete clouds along the line of sight, while diffuse dust produces a time-variable X-ray halo. In the former case, very accurate measures of the distance to the dust clouds can be derived, as well as other characteristics of interstellar dust. Furthermore, the GRB prompt X-ray spectrum, which is typically detected only above virgul15 keV, can be reconstructed from the analysis of the dust-scattered emission and, therefore, extended to the soft X-ray band.|

|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.
