|Title||XMM Observations of X-Ray Emission from Supernovae|
|Author||Mr Stefan Immler|
|Description||The interaction of a supernova (SN) with circumstellar gas gives radiation predominantly in the X-ray range. We propose to make spectral and imaging observations of a small number of young SNe. By comparing the spectra with models for the shock emission, developed by the group, the temperature of the emitting gas, and hence the shock velocity, can be determined. From the low energy cutoff it can be decided whether the shock is radiative or adiabatic. The abundances in the shocked gas reflect whether the reverse shock is in the hydrogen, helium or oxygen rich regions of the SN ejecta. The requested observations, together with our optical, radio and UV data, are hence indispensable to get a detailed picture of both the SN ejecta, shock wave,and|

|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.
