INVESTIGATION OF THE ACTIVITIES IN THE GALACTIC CENTER
The Galactic center (GC) contains many remarkable features resulting from high energy activities: the supermassive black hole (SMBH) Sgr A*, unresolved X-ray emission called as the Galactic center X-ray emission (GCXE), bipolar outflow structures, and X-ray reflection nebulae (XRNe). The main goal of this proposal is to elucidate the origin of the GCXE and to understand the past and present activities in the GC region by plasma diagnostics and measurement of gas dynamics using XRISM.
