论文摘要
我们回顾了我们X射线观察和理论理解的最新发展，以及它们与宇宙网络的联系。淡淡的集群郊区是X射线检查的挑战区域，需要低敏感的望远镜具有低稳定和稳定的背景水平。我们介绍了我们对郊区簇的热力学概况的最新理解，以及气体结块和非热压力支持的偏见。讨论了由于合并活动而引起的郊区的特征，以及郊区ICM的化学富集。我们描述了X射线观察的未来前景，可以在集群郊区进一步探索并探究与宇宙网络的联系。
We review the latest developments in our X-ray observational and theoretical understanding of the outskirts of galaxy clusters, and their connection to the cosmic web. The faint cluster outskirts are challenging regions to observe in X-rays, requiring highly sensitive telescopes with low and stable background levels. We present our latest understanding of the thermodynamic profiles of clusters in the outskirts, and the biases that gas clumping and non-thermal pressure support can introduce. Features in the outskirts due to merging activity are discussed, along with the chemical enrichment of the outskirts ICM. We describe future prospects for X-ray observations to explore further out in the cluster outskirts and probe their connections to the cosmic web.
