Abstract | We propose a ToO observation of a bright (fuence >1e-5 erg cm-2) GRB, located ina 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 expandingX-ray rings are formed by dust scattering of the GRB emission. By studying theserings we can obtain accurate and model-independent measures of the distances tothe dust clouds along the line of sight and probe the properties of their dustgrains (such as the size distribution). Furthermore, the GRB softX-ray spectrum,usually unobserved by GRB instruments, can be reconstructed from the analysis ofthe dust scattered emission. A proposal with identical trigger criteria wasaccepted in AO12, AO15 and AO16 and successfully triggered on GRB160623A. |

Mission Description | The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs 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 Earths 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. |
