Description

Title:Star formation near Sgr A* and the role of cosmic rays in galactic center molecular clouds
Author(s):Yusef-Zadeh, Farhad
Subject(s):Mini-symposium: Astronomical Molecular Spectroscopy in the Age of ALMA
Abstract:I will present recent study of molecular line observations of the Galactic center. On a scale of 2pc from Sgr A*, I show signatures of protostellar outflows within 2pc of Sgr A* based on SiO (5-4), SiO (2-1) line data taken with ALMA, SMA and CARMA. On a larger scale, I discuss the origin of widespread SiO and methanol emission detected from Galactic center molecular clouds. A time-dependent chemical model in which cosmic rays drive the gas chemistry is discussed in order to account for high abundance of SiO and methanol and the high molecular gas temperature.
