We present results of 3 mm observations of SiO maser sources in the Galactic Centre (GC) from observations with the Australia Telescope Compact Array between $2010-2014$, along the transitions of the SiO molecule at $v = 1, J = 2-1$ at 86.243 GHz and $v = 2, J = 2-1$ at 85.640 GHz. We also present the results of the 3 mm observations with Atacama Large Millimeter/Submillimeter Array (ALMA). We detected 5 maser sources from the ATCA data, IRS 7, IRS 9, IRS 10EE, IRS 12N, and IRS 28; and 20… Expand

Sub-millimeter detection of a Galactic center cool star IRS 7 by ALMA
IRS 7 is an M red supergiant star which is located at $5".5$ north of Sagittarius A$^\ast$. We detected firstly the continuum emission at 340 GHz of IRS 7 using ALMA. The total flux density of IRS 7Expand

H2O and SiO maser emission in Galactic center OH/IR stars $O and SiO maser emission in Galactic center OH/IR stars
We have performed targeted surveys for 22 GHz H2O and 43 GHz SiO maser emission in Galactic center OH/IR stars using the Very Large Array. Some of the detections have been used in a previous paper toExpand
SiO Maser Forest at the Galactic Center
A moderately deep survey of stellar maser sources toward the Galactic center has been made in the SiO J=1-0, v=1 and v=2 transitions (~43 GHz) with the Nobeyama 45 m telescope with a beam size ofExpand

Infrared and SiO maser observations of OH/IR stars.
We have performed quasisimultaneous infrared photometry and observations of the SiO 86 GHz (v=1, J=2-1) and SiO 43 GHz (v=1 and 2, J=1-0) maser emission from a sample of 44 OH/IR stars. In contrastExpand
IRS 13N: a new comoving group of sources at the Galactic center
Context. The Galactic center IRS 13E cluster is located ~3.2 '' from SgrA*. It is an extremely dense stellar association containing several Wolf-Rayet and O-type stars, at least four of which show aExpand
SiO maser emission from OH/IR stars close to the galactic centre
A search for 43 (v=1 and 2, J=1→0) and 86 GHz (v=1, j=2→1) SiO maser emission simultaneously was realized from a sample of 31 OH/IR stars close to the Galactic centre using the Nobeyama 45 mExpand
Stellar positions from SiO masers in the Galactic center
We report on the possibility of determining milli- arcsecond accurate positions (relative to Sgr A*) for 43 GHz SiO masers located at the Galactic center. The SiO masers were found in OH/IR stars inExpand
