Title

DIRECT EVIDENCE FOR A PAST OUTFLOW OF THE GALACTIC NUCLEUS SGR A*

Abstract

The objective of the observation is to get the direct evidence of the past outflow of Sgr A*. The key information is the bulk motions of the plasmas of not only the Sgr A bipolar but also the Galactic Center X-ray emission, which may have been created or affected by the Sgr A* outflow. We propose to observe four regions (region N1,N2, S1, S2), which cover the Sgr A bipolar, with 50 ks exposure respectively (total 200 ks).
