Title Improved Shadowing Observations of the Galactic Halo with XMM-Newton

Author Dr David Henley
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.
