项目摘要
9317596 Burns New X-ray, optical, and now radio observations have demonstrated that clusters of galaxies are not simple related structures as once envisioned, but rather dynamically evolving systems that have undergone dramatic cluster/subcluster merging. This research will support a multiwavelength observational study of clusters and cluster merging coupled with sophisticated hydrodynamical and N-body numerical modelling, centered around radio galaxies in clusters. It will investigate how mergers influence the creation and evolution of wide-angle tailed radio sources, cluster radio halos, and steep-spectrum radio galaxies. Numerical hydro/N-body simulations will be used to explore the evolution of the gravitational potential well and the gas in clusters during merging. Magnetohydrodynamic simulations will be used to model the cluster gaseous environment including nonspherical cooling inflows and thermal instabilities, and the propagation of radio jets through cluster atmospheres.
小行星9317596 新的X射线、光学和现在的射电观测表明,星系团并不是曾经设想的简单的相关结构,而是经历了戏剧性的星系团/子星系团合并的动态演化系统。 这项研究将支持对星系团和星系团合并的多波长观测研究,并结合以星系团中的射电星系为中心的复杂流体动力学和N体数值模拟。 它将研究合并如何影响广角尾射电源,集群无线电晕和陡谱射电星系的创建和演化。 数值流体/N体模拟将被用来探索合并过程中的引力势阱和气体的演化。 磁流体动力学模拟将被用来模拟集群的气体环境,包括非球形的冷却流入和热不稳定性,以及无线电射流通过集群大气的传播。
