Abstract A new source of very-high-energy (> 100 GeV) gamma-rays has recently beendiscovered in the interaction region between the Rosette Nebula and theMonoceros Loop SNR (confidential information). This source is unique in both itslocation (in spatial coincidence with a molecular cloud and the limb of an SNR)and its point-like nature. The gamma-ray source is coincident with a weak ROSATX-ray source, but the sensitivity of XMM-Newton is required to identify thenature of this unusual high-energy object.

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.
