报告摘要

By virtue of its proximity, the Galactic center (GC) is a unique and exemplary laboratory for studying a wide array of astronomical phenomena and physical processes. In this talk, I will present an overview of our recent work on the GC, based primarily on Chandra X-ray observations and hydrodynamic simulations. These include: (i) a census of more than 3500 X-ray-emittting, close binaries in the nuclear star cluster; (ii) a clarification of an intermediate-mass black hole candidate in the vicinity of the central SMBH (commonly known as Sgr A*); (iii) X-ray spectroscopic evidence for a type Iax supernova remnant; (iv) a model of the recently discovered GC radio bubbles/X-ray chimneys as a SN-driven, magnetically-collimated outflow; and (v) a proposal for a parsec-scale X-ray jet from Sgr A*.
