|Title||Understanding two new extreme X-ray sources|
|Author||Dr Christian Motch|
|Description||Our optical identification campaign of hard X-ray sources in the XMM-Newton Galactic Plane Survey (XGPS) has revealed two exceptional objects. First, source XGPS-3 is identified with a heavily absorbed very bright infrared source which could be a star as luminous as eta Carina. Second, XGPS-25 has all the features expected from a low-mass X-ray binary whose X-ray emission is strongly shielded by the accretion disc and if confirmed, would be the first very high inclination accretion disc corona known to date. The present proposal aims at obtaining high quality X-ray spectra and time series which will help us to clarify the exact nature of these two objects.|

|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.
