论文摘要
热圆形循环介质（CGM）代表分布在星系的恒星含量之外的热气体，而通常在其暗物质卤个中。它是来自银河反馈的能量和金属富集材料的存放物，以及银河系从中获得燃料形成恒星的储层。因此，它在星系及其环境的共同进化中起着至关重要的作用。 X射线是追踪热CGM的最佳方法之一。在过去的二十年中，我将根据X射线观察结果简要回顾我们对热CGM的了解，以及我们仍然不知道的内容。我还将短暂地展示未来X射线任务的接下来的一到二十年，在接下来的一到二十年中可能会有什么可预见的突破。
The hot circum-galactic medium (CGM) represents the hot gas distributed beyond the stellar content of the galaxies while typically within their dark matter halos. It serves as a depository of energy and metal-enriched materials from galactic feedback and a reservoir from which the galaxy acquires fuels to form stars. It thus plays a critical role in the coevolution of galaxies and their environments. X-rays are one of the best ways to trace the hot CGM. I will briefly review what we have learned about the hot CGM based on X-ray observations over the past two decades, and what we still do not know. I will also briefly prospect what may be the foreseeable breakthrough in the next one or two decades with future X-ray missions.
