Description Clumped gas in cluster outskirts has recently been invoked to explain the thermodynamic state of the ICM observed with Suzaku around the virial radius. Numerical simulations suggest that these clumps will preferentially exist along filaments and that they should be detectable with XMM-Newton due to their compact size. In A1689, Suzaku observations indicate excess emission in the direction of a filament, and ROSAT data suggest the existence of point-like sources just beyond the FOV of the existing XMM-Newton pointing. We propose to detect any compact sources comprising this excess but unrecognized as such due to Suzaku.s large PSF. A second pointing in the direction of a void will help confirm the clumping signature and asses the effect of environment on clumping.

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.
