| Abstract | UGC 10853 is at the center of an optically poor cluster of galaxies (CGCG339-038) with a high X-ray luminosity for its optical richness. It also containsa large diffuse radio source which is likely to be a cluster radio relic orhalo. The galaxy distribution and existing very shallow ROSAT X-ray imagesuggest the cluster is undergoing a merger. We propose the first detailed X-rayobservation (43 ksec) of this poor cluster. We will determine the globalproperties of the cluster and estimate its mass. The dynamical state of thecluster will be studied, and we will derive a likely merger scenario. We willsearch for a merger shock at the sharp NE edge of the radio relic/halo. Thisobservation will extend the study of cluster radio relics to lower mass clusters and groups. |

| 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. |
