    To understand the nature of SiO emission, we conducted ACA observations of the SiO (2-1) lines toward 146 massive starforming regions, as part of the ALMA Three-millimeter Observations of Massive Star-forming regions (ATOMS) ...
  • ATOMS: ALMA three-millimeter observations of massive star-forming regions – XII: Fragmentation and multiscale gas kinematics in protoclusters G12.42+0.50 and G19.88−0.53 
    Saha, Anindya; Tej, Anandmayee; Liu, Hong-Li; Liu, Tie; Issac, Namitha; Lee, Chang Won; Garay, Guido; Goldsmith, Paul F; Juvela, Mika; Qin, Sheng-Li; Stutz, Amelia; Li, Shanghuo; Wang, Ke; Baug, Tapas; Bronfman, Leonardo; Xu, Feng-Wei; Zhang, Yong; Eswaraiah, Chakali (Oxford University Press on behalf of Royal Astronomical Society, 2022-10)
    We present new continuum and molecular line data from the ALMA Three-millimeter Observations of Massive Star-forming regions (ATOMS) survey for the two protoclusters, G12.42+0.50 and G19.88−0.53. The 3 mm continuum maps ...

    Fragmentation and evolution for the molecular shells of the compact H II regions are less explored compared to their evolved counterparts. We map nine compact H II regions with a typical diameter of 0.4 pc that are surrounded ...

O (Oxford University Press on behalf of Royal Astronomical Society, 2024-10)
    It has been suggested that the line width of ions in molecular clouds is narrower than that of the co-existing neutral particles, which has been interpreted as an indication of the decoupling of neutral turbulence from ...
