In the XMM era, enormous strides have been made in understanding the structureof the Galactic Center on scales far too small to be observed in other galaxies.We propose to study the larger scale structure of the Galactic bulge, which maybe readily compared to structures in other galaxies. We propose measuring thetemperature of the soft components of the Galactic X-ray bulge as close to thenucleus as possible, through Baade.s Window. We will then measure the change intemperature with distance from the nucleus. From these measures we expect todetermine the thermal history of the gas in the X-ray emitting bulge and thusthe impact of the central engine on the X-ray bulge.

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.
