Interaction of a massive cluster system with the embedding cosmic filament

The galaxy cluster system RXCJ0225.94154 with the two subclusters A3016 andA3017 embedded in a largescale 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 Xray emission.The main cluster shows indications of shocks most probably from a recent mergeralong the filament axis. The filament between the two subclusters seems to beheated by the accretion shocks of the clusters. To study this rich accretionscenario better than with the available Chandra exposure, we propose anXMMNewton observation of the system for 70 ks. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
