|Title||Jet-Intracluster Medium Interactions of the Head Tail Radio Galaxy 3C 129|
|Author||Dr Henric Krawczynski|
|Description||We propose XMM-Newton obervations of the galaxy cluster 3C 129 which harbors the radio-galaxy 3C 129 (z=0.022). The radio galaxy.s tail extends over 15 arcmin (virgul500 kpc). Chandra observations of 3C 129 show a highly interesting non-uniform Intracluster Medium (ICM) temperature and entropy and indicate that the radio-tail is pinched at a location where the entropy decreases dramatically. The high photon statistics XMM observation will allow us to study in detail the transition region between the high and low temperature ICM. Furthermore, it will be possible to test if the entropy variations can be associated with residuals of large scale structure formation schocks. Finally, the radio-tail-ICM pressure balance can be studied along the full extension of the tail.|

|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.
