Abstract | XMM observations for 50ks of the first unidentified and spatially resolvedsource of very high energy (VHE) gamma-ray emission are proposed. Theseobservations will help to identify the origin of the emission from this sourcedetected at energies above 0.5 TeV (Aharonian et al. 2002,2004). The object (TeVJ2032+4130) is of extended origin with a diameter of 12 arcmin. So far, nocounterpart in any other wavelength has been identified even though thedirection of the TeV source is constrained within a circular region with adiameter of 3 arcmin (68% c.l.). A minimum synchrotron X-ray emission of5x10^{-12} erg/cm^2/s (0.2-12 keV) is expected for a pure leptonic origin of theVHE emission, ideally suited to be detected, resolved and spectrally studied with XMM observations. |

Mission Description | The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs 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 Earths 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. |
