Newly identified extended green objects (EGOs) from the Spitzer GLIMPSE II survey. II. Molecular cloud environments. (2013)

Keywords : infrared ISM - ISM: jets and outflows - radio lines: ISM - stars: formation

Abstract:We have undertaken a survey of molecular lines in the 3mm band toward 57 young stellar objects using the Australia Telescope National Facility Mopra 22m radio telescope. The target sources were young stellar objects with active outflows (extended green objects (EGOs)) newly identified from the GLIMPSE II survey. We observe a high detection rate (50%) of broad line wing emission in the HNC and CS thermal lines, which combined with the high detection rate of class I methanol masers toward these sources (reported in Paper I, Cat. J/ApJS/206/9) further demonstrates that the GLIMPSE II EGOs are associated with outflows. The physical and kinematic characteristics derived from the 3mm molecular lines for these newly identified EGOs ...(more)

A survey for molecular lines in the 3mm band toward ~60% of the GLIMPSE II EGO catalog (Paper I, Cat. J/ApJS/206/9) was performed with the Australia Telescope National Facility (ATNF) Mopra 22m radio telescope in 2009 august 9-20. Fifty-five sites, which include fifty-seven of the GLIMPSE II EGOs were observed in the survey (the two EGO-pairs G352.52+0.76(a)/G352.52+0.76(b) and G358.46-0.39(a)/G358.46-0.39(b) were covered simultaneously within a single Mopra observation).
