|Title||Overionization in supernova remnants: a deep look at the SNR IC 443|
|Author||Ms Eleonora Troja|
|Description||IC 443 is a Galactic supernova remnant with a peculiar morphology: a center-filled thermal X-ray emission within a radio-optical shell. The presence of overionized plasma, addressed in previous works, would be a robust clue to the nature of the center-bright X-rays, which is not yet understood. Our studies show significant spectral variations across the remnant, which may lead to the fictitious detection of overionization. We propose a deep observation of the northeast region in order to obtain a high-quality dataset, and perform a spatially resolved spectroscopy of the brightest X-ray emission of IC 443. We aim to decisively address the issue of overionization, and to constrain the mechanisms of X-ray production from the center of this remnant.|

|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.
