Title:SIO EMISSION FROM THE INNER PC OF SGR A*
Author(s):Yusef-Zadeh, Farhad
Subject(s):Mini-symposium: ALMA's Molecular View
Abstract:A critical question regarding star formation near supermassive black holes (SMBHs) is whether tidal shear completely_x000d_ suppresses star formation or whether it induces star formation. The circumnuclear molecular ring orbiting the 4_x000d_ million solar mass black hole Sgr A* in the inner few parsecs of the Galactic center is an excellent testing ground to_x000d_ study star formation in extreme tidal environments. We have carried out ALMA observations of SiO (5-4) line emission_x000d_ to resolve protostellar outflow candidates in the molecular ring and its interior. We will describe preliminary_x000d_ results of these observations. In addition, we will present _x000d_ ALMA and VLA observations of continuum sources that show bow-shock structures. The characteristics of these mm sources suggest _x000d_ the presence of protoplanetary disks._x000d_ These continuum measurements suggest on-going low-mass star formation_x000d_ with the implication that gas clouds can survive near the strong tidal and radiation fields of the Galactic center._x000d_ _x000d_ _x000d_ _x000d_
