The Magellanic Clouds are surrounded by an extended network of gaseous structures. Chief among these is the Magellanic Stream, an interwoven tail of filaments trailing the Clouds in their orbit around the Milky Way. When considered in tandem with its Leading Arm, the Stream stretches over 200° on the sky. The Stream is thought to represent the result of tidal interactions between the Clouds and ram-pressure forces exerted by the Galactic corona, and its kinematic properties reflect the dynamical history of the pair of dwarf galaxies closest to the Milky Way. The Stream is a benchmark for hydrodynamical simulations of accreting gas and cloud/corona interactions. If the Stream survives these interactions and arrives safely in the Galactic disk, its cargo of over a billion solar masses of gas has the potential to maintain or elevate the Galactic star-formation rate. In this article, we review the current state of knowledge of the Stream, including its chemical composition, physical conditions, origin, and fa...

麦哲伦流：环绕银河系

麦哲伦星云被气态结构的扩展网络所包围。其中最主要的是麦哲伦流，它是一条交织的细丝尾，在它们围绕银河系的轨道上拖着云。当与它的前臂一起考虑时，流在天空中延伸超过 200°。流被认为代表了云与银河日冕施加的撞击压力之间的潮汐相互作用的结果，其运动学特性反映了最接近银河系的一对矮星系的动力学历史。Stream 是吸积气体和云/日冕相互作用的流体动力学模拟的基准。如果流在这些相互作用中幸存下来并安全到达银盘，它装载的超过 10 亿个太阳质量的气体有可能维持或提高银河系的恒星形成率。在本文中，我们回顾了 Stream 的当前知识状态，包括它的化学成分、物理条件、起源和 fa...
