| Abstract | Our optical identification campaign of hard X-ray sources in the XMM-NewtonGalactic Plane Survey (XGPS) has revealed two exceptional objects. First, sourceXGPS-3 is identified with a heavily absorbed very bright infrared source whichcould be a star as luminous as eta Carina. Second, XGPS-25 has all the featuresexpected from a low-mass X-ray binary whose X-ray emission is strongly shieldedby the accretion disc and if confirmed, would be the first very high inclinationaccretion disc corona known to date. The present proposal aims at obtaining highquality X-ray spectra and time series which will help us to clarify the exactnature of these two objects. |

| 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. |
