|Title||Measuring the shock speed in RX J1713.7-3946|
|Author||Dr Fabio Acero|
|Description||These expansion measurements are a powerful way to probe the basic, but often unknown, parameters of the SNR such as age, distance and ambient medium density in which the shock is expanding. In particular, determining the ambient density is a crucial parameter for constraining the fraction of kinetic energy transferred to hadrons accelerated at the front shock of the SNR. In the prototypical accelerator RX J1713.7-3946, no thermal X-ray emission (from the shocked medium) has been observed and proper motion measurement is probably the best way to constrain the ambient density.|

|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.
