最近的结果集群进行审查和讨论有关的冷却流。子星系团的合并在星系团中很常见。这样的合并会破坏冷却流。我认为，最近观察到的发光弧在集群可能是冲击所产生的子集群合并与冷却流。最近的星系团研究所提出的峰值星系分布和径向轨道将导致大量快速运动的星系通过冷却流区，这可能会影响冷却流。最近对星系团质量分布的研究表明，暗物质是中心凝聚的，这可能表明它是耗散的和重子的。我认为，这种暗物质和冷却流中冷却气体的最终储存库可能都是低质量的星星或行星物体。最后，我讨论了各种方式的冷却流环境，这似乎是无处不在的早期型星系系统，形成主机的强射电源，可能会影响的起源和结构的无线电发射区。
Recent results on clusters are reviewed and discussed in relation to cooling flows. Mergers of subclusters are apparently common in clusters. Such mergers will tend to disrupt cooling flows. I suggest that the recently observed luminous arcs in clusters may be shocks generated by a subcluster merger in a cluster with a cooling flow. The peaked galaxy distributions and radial orbits suggested by recent studies of clusters will lead to a larger number of rapidly moving galaxies passing through the cooling flow region, and this may affect the cooling flow. Recent studies of the mass distributions in clusters suggest that the dark matter is centrally condensed; this may indicate that it is dissipative and baryonic. I suggest that this dark matter and the ultimate reservoir of the cooling gas in cooling flows may both be low mass star or planetary objects. Finally, I discuss various ways in which the cooling flow environment, which appears to be ubiquitous in the early-type galactic systems which form the hosts for strong radio sources, may affect the origin and structure of the radio emitting regions.
