| Abstract | The nature of the Galactic diffuse X-ray background (DXB) at low latitudes hasbeen elusive. The ROSAT-detections of the X-ray shadows cast by distantmolecular clouds (d~3 kpc) reveal the existence of a Galactic X-ray bulge (GXB)in addition to the foreground emission to the clouds. As a continuation ofthe DXB study of these multiple Galactic components beyond the capabilities ofROSAT and ASCA, we propose XMM-Newton observations for the uniquely selectedtargets of the X-ray shadows. The proposed observations will provide thebest-ever opportunity for the study of the spectral nature of the multiplecomponents of the Galactic DXB in the plane along the lines of sight. |

| 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. |
