|Title||Testing the Cooling Flow-Galactic Wind Paradigm in Early-type Galaxies|
|Author||Dr Jimmy Irwin|
|Description||Hydrodynamical simulations of the hot gas in elliptical galaxies make strong predictions on the shape of the temperature and surface brightness profiles of the gas depending on if the gas is cooling and flowing inward or flowing out of the galaxy in a wind. X-ray bright galaxies (believed to be in a cooling inflow phase) are well-described by the models. However, to date galaxies likely to be in the outflow phase have been poorly studied due to very low X-ray count rates. Here, we propose an EPIC-pn observation of the prototypical X-ray faint galaxy NGCvirgul4697 to derive the temperature profile of the gas for the first time in an X-ray faint galaxy. The shape of the temperature profile will strictly test the validity of the current cooling flow-galactic outflow paradigm in galaxies.|

|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.
