    We present ALMA Band-3/7 observations towards ‘the Heart’ of a massive hub-filament system (HFS) SDC335, to investigate its fragmentation and accretion. At a resolution of ∼0.03 pc, 3 mm continuum emission resolves two ...
  • ATOMS: ALMA Three-millimeter Observations of Massive Star-forming regions – IX. A pilot study towards IRDC G034.43+00.24 on multi-scale structures and gas kinematics 
    Liu, Hong-Li; Tej, Anandmayee; Liu, Tie; Goldsmith, Paul F; Stutz, Amelia; Juvela, Mika; Qin, Sheng-Li; Xu, Feng-Wei; Bronfman, Leonardo; Evans, Neal J; Saha, Anindya; Issac, Namitha; Tatematsu, Ken’ichi; Wang, Ke; Li, Shanghuo; Zhang, Siju; Baug, Tapas; Dewangan, Lokesh; Wu, Yue-Fang; Zhang, Yong; Lee, Chang Won; Liu, Xun-Chuan; Zhou, Jianwen; Archana Soam (Oxford University Press on behalf of Royal Astronomical Society, 2022-04)
    We present a comprehensive study of the gas kinematics associated with density structures at different spatial scales in the filamentary infrared dark cloud, G034.43+00.24 (G34). This study makes use of the H13CO+ (1–0) ...
  • ATOMS: ALMA three-millimeter observations of massive star-forming regions – VII. A catalogue of SiO clumps from ACA observations

    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 ...
  • First sub-parsec-scale mapping of magnetic fields in the vicinity of a very-low-luminosity object, L1521F-IRS 
    Archana Soam; Lee, C. W; Andersson, B.G; Maheswar, G; Juvela, Mika; Liu, Tie; Kim, Gwanjeong; Ramprasad Rao; Chung, E.J; Kwon, Woojin; Ekta, S S (IOP Publishing, 2019-09-20)
    L1521F is found to be forming multiple cores and it is cited as an example of the densest core with an embedded VeLLO in a highly dynamical environment. We present the core-scale magnetic fields (B-fields) in the near ...
