|Title||X-raying the Giant HII Region G305|
|Author||Prof Marc R. Gagne|
|Description||G305, one of the nearest giant HII regions, contains a WR binary, eight distinct clusters each containing hundreds of stars and eight maser sources and HII regions each containing 4-8 very young O stars. The bubble contains virgul30 O stars suggesting a population virgul15,000 cluster members. A 125-ks ACIS exposure will detect all of the high-mass stars and a high fraction of the low-mass YSOs in central clusters and HII regions. A 60-ks EPIC exposure will do the same in the sparser outer clusters and HII regions. The EPIC observation may detect diffuse emission in the inner cavity or within the optical HII region RCW 74. ACIS and EPIC spectra of the high-mass stars, EPIC and RGS spectra of WR 48a, EPIC spectra of diffuse.|

|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.
