|Title||RGS Observations of Peculiar Knots in Tycho.s SNR|
|Author||Dr Brian Williams|
|Description||Tycho.s SNR provides a pristine laboratory of what remains four and a half centuries after a Type Ia SN. We propose an observation of the southeast portion to observe two bright ejecta knots of interest. Both are Fe-rich, while one contains significant Si as well. RGS observations of these knots will reveal the numerous Fe L-shell and Si lines present, from which we can determine the state of the reverse-shocked ejecta, the thermal line broadening present, search for oxygen, an indicator of a double-degenerate supernova, and possibly measure the time evolution of the Fe K alpha line at 6.5 keV, something never before done. Observations such as these will be crucial for understanding the physics of shocked plasmas in preparation for the next generation of high spectral resolution X-ray observatories.|

|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.
