|Title||Cooling and heating in rotating hot X-ray emitting atmospheres|
|Author||Dr Norbert Werner|
|Description||Observations of massive cooling core clusters and of giant elliptical galaxies indicate that the cold gas in these systems may be produced chiefly by thermally unstable cooling from the hot phase. Recently, there have been considerable numerical efforts to study thermally unstable cooling from the hot into the cold phase. The properties of cooling in the presence of significant angular momentum are, however, likely to be different from cooling in non-rotating atmospheres. Here, we propose a 50 ks observation of NGC 7049, a nearby central group galaxy with a rotating disk of dusty cold gas. We will test predictions for cooling instabilities in systems with significant angular momentum.|

|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.
