| Description | The first TeV gamma-ray survey of the inner part of our Galaxy, recently performed with HESS, yielded eight new sources, seven of which have been identified with radio, X-ray and soft gamma-ray sources. However, TeV J1614-518, a bright, hard-spectrum, extended source, has strikingly elluded identification, notably in the radio and ROSAT bands. We propose XMM-Newton observations to search for its X-ray counterpart. An identification would provide key information about the source type, the spectral high energy distribution and the source spatial structure. Otherwise, the lack of an X-ray counterpart would severely challenge lepton acceleration models and point towards hadronic acceleration or a new, dark class of cosmic 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. |
