| Description | We are proposing shadowing observations of the hot gas in the Galactic halo. Unlike recent shadowing observations, we are proposing to observe compact clouds for which on- and off-cloud spectra can be extracted from a single XMM field. This technique is the only way to ensure that the time-variable contribution due to solar system X-rays is the same in the on- and off-cloud spectra. From these data, we will determine the halo.s X-ray spectrum and measure its temperature and emission measure. This information will help constrain models for the hot halo.s origin. |

| 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. |
