论文摘要
在这里，我对具有延伸的低表面亮度（LSB）氢尾部和相似结构的相互作用的星系系统进行了简要回顾。通常在合并对，星系组和簇中发现的银河系周围环境中的HI特征可以跨越数百个KPC，从而追踪星系和RAM压力力之间的重力相互作用，而RAM压力力通过群体内/群集培养基移动。即将进行的大型HI调查，例如，宽场（FOV = 30平方度）在澳大利亚SKA探路者（ASKAP）上进行的分阶段阵列将提供当地宇宙中LSB结构的普查。通过记录和比较这些观察到的结构及其相关星系的特性（长度，形状，hi质量等），我们可以使用数值模拟 - 尝试建立它们的起源和进化路径。
Here I present a brief review of interacting galaxy systems with extended low surface brightness (LSB) hydrogen tails and similar structures. Typically found in merging pairs, galaxy groups and clusters, HI features in galaxy surroundings can span many hundreds of kpc, tracing gravitational interactions between galaxies and ram pressure forces moving through the intra-group/cluster medium. Upcoming large HI surveys, e.g., with the wide-field (FOV = 30 square degrees) Phased Array Feeds on the Australian SKA Pathfinder (ASKAP), will provide a census of LSB structures in the Local Universe. By recording and comparing the properties (length, shape, HI mass, etc.) of these observed structures and their associated galaxies, we can - using numerical simulations - try to establish their origin and evolutionary path.
