|Title||The Cosmic Ray Production of Mixed Morphology Supernova Remnant Kes 17|
|Author||Prof Joseph Gelfand|
|Description||If galactic supernova remnants (SNRs) are the main producer of cosmic ray protons below <3 PeV, the average remnant must produce virgul10^50 ergs of cosmic rays. However, <10 SNRs show observational evidence for cosmic ray acceleration, and even fewer are producing these particles with the required efficiency. While our recent analysis of SNR Kes 17 suggest it is producing cosmic ray protons, uncertainty about its age, surrounding density, and spectrum of its accelerated electrons, prevents us from measuring the energy of these cosmic rays. With the requested XMM observation we will make these measurement and determine the mechanism responsible for its ..mixed morphology. nature, a class of SNRs associated with cosmic ray production.|

|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.
