Scientific paper

We have analyzed the ˜ 0.6 Ms Chandra deep exposure data and resolved several non-thermal X-ray knots located near the Galactic center (GC). In particular, we focused on three prominent X-ray knots which are aligned from the GC to the north-northwest direction. All of the three X-ray knots have an elongated shape toward the same direction (from GC to north-northwest). The major and minor axes of these knots are typically ˜ 6 arcsec and ˜ 2.5 arcsec. The X-ray spectrum of each knot exhibits no line emissions, therefore their origin should be non-thermal. By comparing Very Large Array 6 cm and 20 cm continuum maps, we found radio structures are marginally coincident with these X-ray knots. Above observational results suggest that these knots are jet-like objects ejected from the Galactic nucleus (Sgr A*), so we also try to estimate the proper motion velocity of these knots. Although we can obtain the upper limit of their motion, it suggests that these knots have a possible correlation with > 400 years past activity of Sgr A*.
