CH_3_OH maser survey of EGOs
Listed in IVOA Registry (Virtual Observatory)
Description
We present the results of a high angular resolution Very Large Array (VLA) Class I 44GHz and Class II 6.7GHz CH_3_OH maser survey of a sample of ~20 massive young stellar object (MYSO) outflow candidates selected on the basis of extended 4.5um emission in Spitzer Galactic Legacy Infrared Mid-Plane Survey Extraordinaire images. These 4.5um selected candidates are referred to as extended green objects (EGOs), for the common coding of this band as green in three-color Infrared Array Camera images.
The detection rate of 6.7GHz Class II CH_3_OH masers, which are associated exclusively with massive YSOs, toward EGOs is >~64% - nearly double the detection rate of surveys using other MYSO selection criteria. The detection rate of Class I 44GHz CH_3_OH masers, which trace molecular outflows, is ~89% toward EGOs associated with 6.7GHz CH_3_OH masers.
