| Abstract: |
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. |
