|Title||The unidentified source HESS J1702-420 and the possible nebula of PSR J1702-4128|
|Author||Dr Yves Gallant|
|Description||We propose XMM-Newton observations to examine the nature of the unidentified VHE gamma-ray source HESS J1702-420. The VHE morphology shows a tail towards PSR J1702-4128, and we propose deeper X-ray observations of a field containing this pulsar to confirm if it exhibits an asymmetric X-ray nebula, for which there is some evidence in archival ASCA data. If so, this would be the oldest and least energetic pulsar yet found to power a VHE and X-ray nebula. The proposed exposure should also allow a confirmation of the more localised excess seen at the pulsar position with Chandra. Finally, the proposed observation would also more than triple the XMM-Newton exposure on G344.7-0.1, a supernova remnant which shows some evidence of containing a plerionic component.|

|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.
