|Title||Understanding the Physics and Dynamics of NGC4839 Group as It Falls into Coma|
|Author||Dr William Forman|
|Description||An 80 ks XMM-Newton observation, along with a 40 ks Chandra pointing, of the massive group centered on the cD galaxy NGC4839, which is falling into the Coma cluster core, will provide the first excellent map of the merging subcluster and allow the physics and dynamics of this merger to be studied in unprecedented detail. The proposed observations will determine the nature of the hot core in NGC4839, including the AGN outburst power. We also will measure the total (3D) velocity of the merging group and the properties of the shock-sheath region at the interface between the Coma ICM and the group gas, and finally, will compute the gas mass in NGC4839.s 400 kpc tail to determine the importance of mixing of cluster gas with the stripped group gas.|

|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.
