Recent X-ray observations of the composite SNR G327.1-1.1 have revealed complexstructure in the central PWN. The likely counterpart to the associated neutronstar has been identified, and it is embedded in a bow-shock like structure atthe tip of a long X-ray tail. Elongated structures protrude opposite the tail;their nature is not at all understood. Faint thermal emission from the SNR shellis detected, but its properties are so poorly measured that a reliable age fromwhich the pulsar velocity can be estimated does not currently exist. We proposea deep XMM-Newton observation in order to map the spatial and spectral structureof the extended PWN features and to derive the spectral properties of thethermal shell. A pulsation search will also be conducted.

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.
