What is ATCA Detection of SiO Masers in the Inner Parsecs of the Galactic Center about?

We present sensitive Australia Telescope Compact Array (ATCA) observations of SiO masers in the inner parsecs of the Galactic center (GC). We detected five SiO J=2-1, v=1 (86 GHz) masers in the innner 25 arcsec (1 pc) of the GC. All the detected 86 GHz SiO masers are previously known SiO J=1-0, v=1 (43 GHz) masers and associated with late-type stars. Eighteen 43 GHz SiO masers were detected within 50 arcsec (2 pc) of Sagittarius A*. Among them, seven are detected for the first time, which brings the total number of 43 GHz SiO masers to 22 in this region.
