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

| 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. |
