| Abstract | Composite supernova remnants (SNRs) display the characteristics of both a standard shell-type SNR as well as a compact nonthermal component powered by a central object. A crucial aspect of their study is the ability to separate spatially and spectrally these two components. We propose observation of two remarkable composite SNRs MSH 11-62 and G39.2-0.3. Both objects present strongevidences of a central engine powering a synchrotron nebula as well as a thermalcomponent. The proposed observations will: map the two contributions, charac-terize their respective properties and constrain both the central engine -andmaybe discover X-ray pulsations- and the dynamical state of the remnants. Thiswill help build a general picture of the ever-growing class of composite SNRs. |

| 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. |
