|Title||The Hot Winds of Ultraluminous Infrared Galaxies|
|Author||Prof Crystal Martin|
|Description||Ultraluminous infrared galaxies (ULIGs) represent an important stage in the birth of an ellipitcal galaxy. They are powered largely by starbursts which may drive massive galactic winds. These outflows likely affect the chemical evolution of ellipticals, heat the intergalactic medium, and unveil nascent quasars. From a large Keck II spectroscopic survey, I have selected two ULIGs with strong, blueshifted interstellar absorption lines. These cold clouds must be entrained in a hot outflow. Measurement of the temperature and emission measure of the hot wind are needed to describe the dynamics of the outflow. Only XMM provides the sensitivity required for this spectral analysis, but additional Chandra observations would greatly aid in their interpretation.|

|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.
