Abstract	G296.8-0.3 is an unusual supernova remnant (SNR) in Crux. Radio observationshave revealed an intricate multiple-shell structure with sharp radio filaments,and a peculiar strip running across its center. The Spitzer Space Telescope hasrevealed sharp infrared (IR) filaments at 24 microns matching synchrotron radiofilaments. The IR emission is most likely produced by dust immersed within thehot X-ray emitting plasma. Little is known about G296.8-0.3, and the origin ofits peculiar morphology remains unexplained. We propose a spatially-resolvedX-ray spectroscopy of G296.8-0.3 with the XMM-Newton EPIC camera. We will deriveshock speeds, infer densities, pressures, and abundances in the X-ray emittinggas, allowing us to learn about the true nature of this mysterious SNR.

Mission Description	The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs 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 Earths 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.
