|Title||Gamma-Ray bursts as probes to study interstellar dust, and vice versa|
|Author||Prof Andrea Tiengo|
|Description||We propose a ToO observation of a bright (fuence >1e-5 erg cm-2) GRB, located in a sky direction with significant amount of dust along the line of sight (Av>0.5). As already observed in a few cases, in these conditions expanding X-ray rings are formed by dust scattering of the GRB emission. By studying these rings we can obtain accurate and model-independent measures of the distances to the dust clouds along the line of sight and probe the properties of their dust grains (such as the size distribution). Furthermore, the GRB softX-ray spectrum, usually unobserved by GRB instruments, can be reconstructed from the analysis of the dust scattered emission. A proposal with identical trigger criteria was accepted in AO12, AO15 and AO16 and successfully triggered on GRB160623A.|

|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.
