论文摘要
围绕大型星系周围的气态X射线光环的存在是所有过去和现代结构形成模拟的基本预测。这些X射线光环的重要性进一步强调了以下事实：它们保留了塑造星系从最高红移到今天的物理过程的签名。在这篇综述中，我们概述了我们当前对附近大型星系周围热气体X射线光环的观察和理论理解，我们还描述了使用未来工具观察X射线光环的前景。
The presence of gaseous X-ray halos around massive galaxies is a basic prediction of all past and modern structure formation simulations. The importance of these X-ray halos is further emphasized by the fact that they retain signatures of the physical processes that shape the evolution of galaxies from the highest redshift to the present day. In this review, we overview our current observational and theoretical understanding of hot gaseous X-ray halos around nearby massive galaxies and we also describe the prospects of observing X-ray halos with future instruments.
