| Abstract | The 3-dimensional structure of the X-ray emitting hot plasmas along the lines ofsight to make up the observed 0.5-2 keV X-ray background is unknown. The onlyway to unveil the 3-D distribution of the soft X-ray emitting Galactic hotplasmas is to discover and study X-ray shadows cast by dense molecular cloudsat known distances. We have performed such X-ray shadow experiments withXMM-Newton observations awarded in AO2 cycle, but our data were severelycontaminated by the flaring particle background. We therefore request foranother set of X-ray shadow observations, including repeat of the previouslyawarded targets. |

| 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. |
