银河系中心的高能辐射概述

An overview of the high-energy emission from the Galactic Center

Andrea Goldwurm

摘要:

银河系中心是X射线和伽马射线的主要来源,研究其高能发射对于理解在其密集和极端环境中发生的物理现象至关重要,这些现象可能是其他星系核所共有的。然而,这种发射也是非常复杂的,包括由紧凑和扩展的源产生的热和非热辐射,被更多的漫射成分包围。尽管在过去的十年中取得了根本性的进展与钱德拉,XMM-牛顿,积分,HESS和朱雀几个问题仍然开放的调查。我将在这里回顾银河系核活动高能诊断的主要结果和公开问题。

英文摘要:

The Galactic Center is a prominent source in X-rays and gamma-rays and the study of its high-energy emission is crucial in understanding the physical phenomena taking place in its dense and extreme environment, phenomena that are possibly common to other galactic nuclei. However this emission is also very complex and consists of both thermal and non thermal radiation produced by compact and extended sources, surrounded by more diffuse components. In spite of the fundamental advances obtained in the last ten years with Chandra, XMM-Newton, INTEGRAL, HESS and Suzaku several questions remain open to investigations. I will review here the main results and the open issues on the high-energy diagnostic of the galactic nuclear activity.
