|Title||THE QUEST OF THE SHOCK IN THE MERGING CLUSTER A3667|
|Author||Dr FABIO GASTALDELLO|
|Description||One of the interesting chandra discoveries is the existence of sharp gas density edges in some galaxy clusters. There are two different types of such features, depending on the sign of their temperature jump: a cold front and a merger bow-shock. A3667 is the most striking example of cold front and with a possible evidence of a bow shock. Existing chandra and xmm observation do not allow to firmly establish the nature of the outer surface brightness jump: we thus propose a long on-axis observation to exploit the large effective area of EPIC in order to measure the sign of the temperature jump across the outer discontinuity.|

|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.
