摘要我们分析了大质量星系群NGC 4839落入后发座星系团核心的档案XMM-牛顿观测，揭示了合并的复杂形态。通过比较高质量的X射线地图的合并子集群与SPH模拟，我们提出了一个坠落的情况下，定性再现观察到的结构的NGC 4839尾巴。
Abstract We analyse archival XMM-Newton observations of the massive galaxy group NGC 4839 falling into the Coma cluster core, which reveal a complex morphology for the merger. By comparing high quality X-ray maps of the merging subcluster with SPH simulations, we propose an infall scenario which qualitatively reproduces the observed structure of the NGC 4839 tail.
