    • An ALMA Survey of DCN/H13CN and DCO+/H13CO+in Protoplanetary Disks 

      Huang, Jane; Oberg, Karin; Qi, Chunhua; Aikawa, Yuri; Andrews, Sean; Furuya, Kenji; Guzman, Viviana; Loomis, Ryan; van Dishoeck, Ewine; Wilner, David (American Astronomical Society, 2017-01-31)
      The deuterium enrichment of molecules is sensitive to their formation environment. Constraining patterns of deuterium chemistry in protoplanetary disks is therefore useful for probing how material is inherited or reprocessed ...

    • Dissecting the Molecular Structure of the Orion B Cloud: Insight From Principal Component Analysis 

      Gratier, Pierre; Bron, Emeric; Gerin, Maryvonne; Pety, Jérôme; Guzman, Viviana; Orkisz, Jan; Bardeau, Sébastien; Goicoechea, Javier; Le Petit, Franck; Liszt, Harvey; Oberg, Karin; Peretto, Nicolas; Roueff, Evelyne; Sievers, Albrech; Tremblin, Pascal (EDP Sciences, 2017-03)
      Context: The combination of wideband receivers and spectrometers currently available in (sub-)millimeter observatories deliver wide-field hyperspectral imaging of the interstellar medium. Tens of spectral lines can be ...

    • H2CO Distribution and Formation in the TW HYA Disk 

      Oberg, Karin; Guzman, Viviana; Merchantz, Christopher; Qi, Chunhua; Andrews, Sean; Cleeves, Lauren; Huang, Jane; Loomis, Ryan; Wilner, David; Brinch, Christian; Hogerheijde, Michiel (American Astronomical Society, 2017-04-12)
      H2CO is one of the most readily detected organic molecules in protoplanetary disks. Yet its distribution and dominant formation pathway(s) remain largely unconstrained. To address these issues, we present ALMA observations ...
