    • Detection of infall in the protostar B335 with ALMA 
      Evans II, Neal J.; Di Francesco, James; Lee, Jeong-Eun; Jørgensen, Jes K.; Choi, Minho; Myers, Philip C.; Mardones Pérez, Diego (The American Astronomical Society, 2015)
      Observations of the isolated globule B335 with ALMA have yielded absorption features against the continuum that are redshifted from the systemic velocity in both HCN and HCO+ lines. These features provide unambiguous ...

      We present the results of a single-pointing survey of 207 dense cores embedded in Planck Galactic Cold Clumps distributed in five different environments (lambda Orionis, Orion A, Orion B, the Galactic plane, and high ...

      We present the results of on-the-fly mapping observations of 44 fields containing 107 SCUBA-2 cores in the emission lines of molecules N2H+, HC3N, and CCS at 82-94 GHz using the Nobeyama 45 m telescope. This study aimed ...
