Abstract | The emission from the Local Hot Bubble (LHB) has been observed to have agradient in its ROSAT color. Given the large effective area and resolution ofthe EPIC, we propose to measure more precisely the strength of this gradientwithin the Galactic plane. Determining the nature of this variation hasapplication beyond studies of the interstellar medium; since the O VII and OVIII lines are expected to dominate the spectrum of the Galactic halo, the samelines are the most promising means of detecting the hot extragalactic medium,and the LHB emission should be dominated by these lines, it is essential tounderstand the variation in the LHB emission spectrum in order to study theGalactic halo and (possibly) detect the extragalactic medium. |

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. |
