Title Investigation of X-ray properties of H.E.S.S. Galactic unidentified sources


DOI 10.5270/esa-hsze5ft
Author Dr Stefan Funk
Description In a survey of the Galactic plane performed in 2004 with the H.E.S.S. instrument a new class of so far unidentified very high energy gamma-ray sources was discovered. We propose to use XMM-Newton to perform follow-up observation on a set of three of the newly discovered sources, for which searches in existing multi-waveband data have not revealed any counterparts. The sensitivity of XMM-Newton would be required to identify possible X-ray counterparts of the VHE gamma-ray sources, despite the obscuration by gas in the Galactic plane. This would allow to obtain morphological and spectral information of possible counterparts and will help to understand the physical nature of the emission mechanisms in this new class of ..dark.. astrophysical 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.
