Abstract We propose to study a complete X-ray sample in the luminosity of 0.5-5 x 10^35erg/s in the Galactic bulge, containing 10 unidentified sources detected in theROSAT All Sky Survey. Our goal is to obtain, for the first time, a clear pictureabout X-ray populations in the bulge with detailed X-ray spectroscopic studiesof these sources. This is a new step toward understanding the formation historyof the bulge, and hence that of galaxies with various Hubble sequences in theuniverse. Furthermore, because the luminosity range we observe corresponds to amissing link.. region ever studied for a neutron star or blackhole X-raybinary, our results are also unique to test accretion disk theories atintermediate mass accretion rates.

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.
