|Title||Supernova Remnants in X-Rays and Infrared: 0453.1-66.55 and DEM L204|
|Author||Dr Kazimierz Borkowski|
|Description||Recent observations of supernova remnants (SNR) with the Spitzer Space Telescope revealed that thermal dust emission dominates their infrared (IR) spectra. IR emission was detected mostly in X-ray bright SNRs, but it is also present in several older and fainter SNRs. We propose an X-ray study of two such IR remnants, 0453.1-66.55 and DEM L204. The origin of IR emission and the nature of these SNRs are not understood. X-ray imaging with the XMM-Newton EPIC camera will reveal location of the hot gas relative to optical and IR emission, allowing us to understand the origin of the IR emission. X-ray spectroscopy will provide as with temperatures and abundances of the hot gas. We will learn about dust content, energetics, and the evolutionary state of these unusual infrared SNRs.|

|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.
