GBT Observations of the Star-Forming Regions DR21 and MonR2 with the new Argus Instrument
Abstract
We present GBT molecular line observations of DR21 and MonR2 with the new 16 element 75--115 GHz Argus instrument. Both molecular cloud complexes are associated with regions of high-mass star formation. We present the results of our 13CO, C18O, and HCO+ observations. Both MonR2 and DR21 show multiple velocity components, and the data suggest that the core of MonR2 is collapsing, while DR21 contains a region with a strong outflow traced by HCO+.
