| Abstract | MACS J1931.8-2634 is a star-forming galaxy cluster at z~0.35. Thearchival Chandra CCD spectra suggest a rather low level of metallicity inthe intracluster media out to ~400 kpc. No other metal abundances weremeasured with the CCD data. AGN bubbles might explain the observed abundancebut it is unclear whether dust plays an essential role. Here we propose toobserve this target using mainly RGS with a total exposure of 188 ks.We will accurately measure the metal abundances of O, Ne, and Fe. Thisenables us to verify whether metals in the cluster core are locked into dustand moved away towards the cluster outskirt. |

| Mission Description | The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs 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 Earths 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. |
