|Title||Search for X-ray counterparts of Galactic TeV sources discovered by H.E.S.S.|
|Author||Mr Stefan Funk|
|Description||During a scan of the Galactic plane performed in 2004, H.E.S.S. (the currently most sensitive TeV telescope) has discovered a new class of so far unidentified TeV gamma-ray sources. We propose to use XMM to perform follow-up observations on several of these sources, for which exhaustive searches in existing broadband data have revealed no obvious counterparts. The large sensitivity of XMM and its energy range up to 15 keV is required to identify the X-ray counterparts of the TeV sources despite the obscuration by gas in the Galactic plane, and will allow us to obtain morphological and spectral information which will help to identify the physical nature of this new class of high energy gamma-ray sources.|

|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.
