|Title||The X-ray Spectra of Ultraluminous Infrared Galaxies (ULIRGs)|
|Author||Prof Andrew Wilson|
|Description||Ultraluminous Infrared Galaxies are fundamentally r^ant to a wide range of astronomical issues. However, the power source for the huge infrared luminosity is uncertain: it could be a ..starburst. or an active galactic nucleus and we argue that X-ray observations provide the best method of resolving this issue. We have observed a sample of 14 ULIRGs with Chandra. These galaxies were carefully chosen to sample the full range of galaxy properties, rather than the brightest or best known examples. With XMM we will obtain spectra of the 8 galaxies in our Chandra-observed sample which have not been observed by XMM, and then make a comprehensive study of the X-ray properties of the full sample, using both XMM and Chandra observations.|

|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.
