Star Formation and Jet Interactions near Sgr A*

There are several sources of interest in the unique region of the Galaxy surrounding Sgr A*. I will focus on two topics related to the supermassive black hole Sgr A* which lies at the dynamical center of the Galaxy. One relates to a three earth mass gas cloud called G2 which is on a collision course with Sgr~A*. We consider the possibility that the gas cloud G2 approaching Sgr A* may encounter a relativistic jet-driven outflow. We present the light curves of Sgr A* at X-ray and radio wavelengths during which G2/Sgr A* interact with each other. I will argue that the origin of how young stellar disks are formed in the context of the passage of a giant molecular cloud interacting with Sgr A*. I will also present ALMA measurements supporting on-going star formation near Sgr A*.
