X-ray activities in the Galactic Center region [link]Website  abstract   bibtex   
With ASCA, we obtained detailed X-ray images and spectra of the Galactic Center. X-rays in the central parsecs from the dynamical center of the Galaxy, Sgr A*, were dominated by extended emission. Since Sgr A* was not spatially resolved from the extended structure, an upper limit to its luminosity was found to be 3 × 1035 erg s-1. This result indicates that the current AGN activity of the Galactic nucleus is very low. In the central hundreds of parsecs, X-ray stars, thin thermal diffuse plasma, and iron fluorescent emission from molecular clouds were seen. Based on the analyses of the X-ray stars and both of the diffuse components, we discuss some features which are possibly related to past nuclear activities.
