H2O and SiO masers in the Galactic center
Listed in IVOA Registry (Virtual Observatory)
We have performed targeted surveys for 22GHz H_2_O and 43GHz SiO maser emission in Galactic center OH/IR stars using the Very Large Array.
Description
Some of the detections have been used in a previous paper to investigate the possibility of measuring milli-arcsecond accurate positions (to obtain stellar proper motions) in the Galactic center. Here we report on the detection of at least 25 H_2_O masers and 18 SiO masers associated with stars within 2{deg} and 15' of Sgr A*, respectively.
This survey has more than doubled the total number of proper motion candidates to at least about 50 stellar objects.
