Abstract The detection of non-thermal X-ray emission from supernovas remnants (SNRs)provides us a unique window to study particle acceleration at their shock-front.All of the ~14 SNRs in which non-thermal X-ray synchrotron emission has beendetected are shell-like in nature, and show no evidence of interaction withlarge nearby molecular clouds. We propose a deep XMM and NuSTAR observation ofSNR G346.6-0.2, which is a rare case of a molecular cloud interacting,mixed-morphology SNR that shows non-thermal X-ray emission. These observationswill allow us to constrain and characterise the power-law tail, better definethe thermal X-ray properties across the remnant, determine the effect that adense environment has these properties, as well as the plasma conditions which lead to nonthermal X-rays.

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.
