|Title||Probing the Environments of Young Supernovae with XMM-Newton|
|Author||Dr Stefan Immler|
|Description||By observing the X-ray emission properties of young supernovae (SNe), physical key parameters such as the circumstellar matter (CSM) density, the mass-loss rate of the progenitor, and the temperature of the outgoing and reverse shock can be studied as a function of time. We propose follow-up observations of the brightest known X-ray emitting SNe (1978K, 1979C, 2004dj) to study the temperature evolution, establish the physical parameters of the ambient CSM out to radii of E18cm from the sites of the explosions, and to monitor the mass-loss rates over 10^4 years in the progenitors stellar wind history. Studying these key parameters as a function of time has never been done before.|

|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.
