|Title||Searching for the Thermal Plasma in the Naked Pulsar Wind Nebula CTB 87|
|Author||Prof Samar Safi-Harb|
|Description||The missing thermal X-ray emission from dozens of naked pulsar wind nebulae (PWNe) remains one of the most puzzling questions in the SNR field. Our understanding of PWNe has been largely biased by the study of the brightest and youngest objects, such as the Crab nebula. We propose a deep EPIC observation of CTB 87. Our Chandra study, complemented with multi-wavelength observations, suggests that this remnant is an evolved PWN, most likely crushed by the supernova explosion.s reverse shock. Alternatively, a bow-shock interpretation is also plausible. Our proposed observation will discriminate between these two scenarios. XMM-Newton is the ideal facility to perform a deep search for the thermal emission expected at the PWN-reverse shock interaction site and from the long-sought SNR shell.|

|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.
