    • Massive outflows associated with ATLASGAL clumps 

      Yang, Aiyuan; Thompson, Mark; Urquhart, James; Tian, Wenwu (2018-03-01)
      We have undertaken the largest survey for outflows within the Galactic plane using simultaneously observed 13COand C18O data. Out of a total of 919 ATLASGAL clumps, 325 have data suitable to identify outflows, and 225(69% ...
