早型星系的X射线辐射
X-ray emission from early-type galaxies
摘要：
在过去的十年中，对本机宇宙早期星系的X射线研究取得了很大进展，由于钱德拉和XMM-牛顿卫星的高角分辨率和灵敏度，人们首次尝试使这些天体的红移达到z>0。我们对X射线发射的三个独立贡献者，即恒星源、热气体和星系核的认识已经取得了重大进展。这里的主要结果的简要概述，指出仍然开放的问题，最后讨论的前景，以解决他们的广域X射线调查任务，如WFXT。
英文摘要：
The past decade has seen a large progress in the X-ray investigation of early-type galaxies of the local universe, and first attempts have been made to reach redshifts z>0 for these objects, thanks to the high angular resolution and sensitivity of the satellites Chandra and XMM-Newton. Major advances have been obtained in our knowledge of the three separate contributors to the X-ray emission, that are the stellar sources, the hot gas and the galactic nucleus. Here a brief outline of the main results is presented, pointing out the questions that remain open, and finally discussing the prospects to solve them with a wide area X-ray survey mission such as WFXT.
