Diffuse X-ray spectrum of our galactic center.
Abstract
An extended high temperature plasma associated with Kα lines of highly ionized atoms is found near the galactic center region. Fluorescent X-ray emissions from cold iron in molecular clouds were also found, due possibly to an irradiation by an X-ray source which was bright in the past but is dark at present. These results suggests that the galactic center exhibited intermittent activities with time-averaged energy comparable to Seyfert nuclei, a class of active galactic nuclei.
