ALMA Observations of the Galactic Center: SiO Outflows and High Mass Star Formation Near Sgr A.

摘要

Using ALMA observations of the Galactic center with a spatial resolution of 2.61' x 0.97', we detected 11 SiO (5-4) clumps of molecular gas in the within 0.6pc (15') of Sgr A*, interior of the 2-pc circumnuclear molecular ring. Three SiO (5-4) clumps clos
