An unbiased survey for high-velocity gas in the Monoceros OB1 molecular cloud

A sensitive and uniformly sampled map of CO (J = 1-0) emission over a large fraction of the Mon OB1 (NGC 2264) molecular cloud has been obtained in order to make an unbiased survey for high-velocity gas in a single molecular cloud. High-velocity line wings (i.e., v > 10 km s-1) were detected on profiles over roughly 10% of the region surveyed. The strongest high-velocity emission was found to originate in nine distinct sources which are likely to be molecular outflow sources. However, in only three cases does the high-velocity emission exhibit bipolar morphology. Thirty infrared point sources were identified within the boundaries of the CO survey from 12, 25, and 60 μm IRAS maps. Only 2/3 of the molecular outflows may be associated with these sources.
