    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) ...

    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

Viktor (American Astronomical Society, 2024-03-01)
    High-latitude (|b| > 30°) molecular clouds have virial parameters that exceed 1, but whether these clouds can form stars has not been studied systematically. Using JCMT SCUBA-2 archival data, we surveyed 70 fields that ...
