Title The chemistry of interstellar dust through the scattering halo of Cyg X-2

Author Dr Elisa Costantini
Description We propose to observe the bright X-ray source Cyg X-2 as an ideal candidate to study the chemistry of the diffuse Interstellar Medium (ISM). We will study the two phases of ISM (gas and dust) through spectroscopy of the absorbed spectrum and the spectral and spatial analysis of the X-ray dust scattering halo. The study of the scattering halo of Cyg X-2 unveiled for the first time features from the ID constituents. To perform a quantitative measurement of the chemistry of the Interstellar Dust (ID) grains a large collective area, a large field of view, and a broad band coverage, like the one provided by XMM, is needed.

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.
