|Title||NGC 499 - Mapping the merger of two X-ray luminous galaxy groups|
|Author||Dr Ewan O.Sullivan|
|Description||We propose an observation of NGC 499 which, with NGC 507, forms one of the best examples of a group-group merger in the local universe. Excellent archival XMM data for NGC 507 is available, and with this new observation we will be able to produce high resolution spectral maps of both groups and the gas between them, providing a wealth of data on the effects of the merger on the two systems. We will search for signs of tidal or viscous stripping and gas compression, and produce models of the temperature, abundance and mass distribution out to virgul600 kpc, providing detailed information on the structure of the two systems and shedding light on this important stage in the evolution of groups.|

|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.
