|Title||The nature of a newly discovered Galactic TeV source with variable GeV emission?|
|Author||Mrs Sarah Kaufmann|
|Description||In the HESS survey of the Galactic plane performed in 2006-2008, many new VHE gamma-ray sources have been discovered and most of them are still unidentified. One interesting newly discovered source has several positional counterparts: a SNR, two rather powerful pulsars and several unidentified sources in the hard X-ray range and at GeV energies, that are suggested to be variable. Recently a GeV pulsar has been detected in this region by Fermi. We propose for a 25ks XMM-Newton observation on this source to study if the TeV and the GeV source are physically connected and to shed light on their nature. The aim is to obtain morphological and spectral information on the possible X-ray counterparts in order to better understand the emission mechanism of this source(s).|

|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.
