Description We propose to perform spatially resolved spectroscopy of the Ophiuchus cluster
of galaxies over spatial scales of 100 kpc to map its temperature, metal
abundance and emission measure structures. We also aim to resolve the ionization
temperature structure using the flux ratio of the FeXXV and FeXXVI lines.
Comparing the ionization temperatures with continuum-derived temperatures
enables the mapping of the non-thermal component and thus removing the bias in
the continuum-based temperature measurement. This information will provide
insights into the merger scenario.

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.
