The galaxy cluster system RXCJ0225.9-4154 with the two sub-clusters A3016 andA3017 embedded in a large-scale structure filament shows very excitingsignatures of filamentary accretion. The filament can be traced over 6 Mpc bygalaxies and over more than half of its length we observe it in X-ray emission.The main cluster shows indications of shocks most probably from a recent mergeralong the filament axis. The filament between the two sub-clusters seems to beheated by the accretion shocks of the clusters. To study this rich accretionscenario better than with the available Chandra exposure, we propose anXMM-Newton observation of the system for 70 ks.

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.
