Title Resolving the structure of solid dust particles towards Cygnus X-2

Author Dr Cor de Vries
Description We aim to search for extended X-ray absorption fine structures (EXAFS), in the direction of Cygnus X-2. This is driven by the recent significant detection by our group of EXAFS absorption in spectra in the line of sight towards Sco X-1, which opens up a new frontier in the study of interstellar dust. We now have the possibility to probe the details of the composition and solid structure of interstellar dust particles by direct observations. By resolving EXAFS structures in different line of sights we will enable a clearer identification of the solid materials of which the dust particles are made of and will help to resolve questions on the generation and evolution of interstellar dust particles.

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.
