| dc.description | This paper reports on the early Chandra view of the Galactic center (GC) activities. The massive black hole Sgr A* is extremely faint, while more bright diffuse X-ray emission is prevailing in the circumnuclear disk. Another high temperature plasma is found in the Sgr A East shell. This may indicate that Sgr A East is a supernova remnant, although no clear X-ray shell is found. A hint of non-thermal X-ray filaments is found, suggesting the presence of an acceleration site of extremely high-energy cosmic rays. The giant molecular cloud Sgr B2 is established to be an X-ray reflection nebula, possibly arising from the past Sgr A activities. Chandra further discovered high temperature shells, suggesting multiple supernova explosions near the GC region. | |
