    • Revealing the CO X-factor in Dark Molecular Gas through Sensitive ALMA Absorption Observations 
      Luo, Gan; Li, Di; Tang, Ningyu; Dawson, J. R.; Dickey, John; Bronfman Aguiló, Leonardo; Qin, Sheng-Li; Gibson, Steven; Plambeck, Richard; Finger Camus, Ricardo; Green, Anne J.; Mardones Pérez, Diego; Koo, Bon-Chul; Lo, Nadia (IOP, 2020)
      Carbon-bearing molecules, particularly CO, have been widely used as tracers of molecular gas in the interstellar medium (ISM). In this work, we aim to study the properties of molecules in diffuse, cold environments, where ...
    • Where is OH and Does It Trace the Dark Molecular Gas (DMG)? 
      Li, Di; Tang, Ningyu; Nguyen, Hiep; Dawson, J.; Heiles, Carl; Xu, Duo; Pan, Zhichen; Goldsmith, Paul; Gibson, Steven; Murray, Claire; Robishaw, Tim; McClure-Griffiths, N.; Dickey, John; Pineda, Jorge; Stanimirović, Snežana; Bronfman Aguiló, Leonardo; Troland, Thomas (Institute of Physics Publishing, 2018)
      Hydroxyl (OH) is expected to be abundant in diffuse interstellar molecular gas because it forms along with H2 under similar conditions and forms within a similar extinction range. We have analyzed absorption measurements ...
