We report the observations of J=1-0 of HCN, HCO+, H13CO+, and H13CN, HC3N (J=11-10) emission towards 135 massive star-forming clumps, as part of the ATOMS (ALMA Three-millimeter Ob…
ATOMS: ALMA three-millimeter observations of massive star-forming regions -- XVIII. On the origin and evolution of dense gas fragments in molecular shells of compact HII regions
Siju Zhang, Tie Liu, Ke Wang +16
Fragmentation and evolution for the molecular shells of the compact HII regions are less explored compared to their evolved counterparts. We map nine compact HII regions with a typ…
JCMT 850 $\micron$ continuum observations of density structures in the G35 molecular complex
Xianjin Shen, Hong-Li Liu, Zhiyuan Ren +32
Filaments are believed to play a key role in high-mass star formation. We present a systematic study of the filaments and their hosting clumps in the G35 molecular complex using JC…
A High-Mass Young Star-forming Core Escaping from Its Parental Filament
Zhiyuan Ren, Xi Chen, Tie Liu +17
We studied the unique kinematic properties in massive filament G352.63-1.07 at -AU spatial scale with the dense molecular tracers observed with the Atacama Large Millimeter/s…
The ALMA Survey of Star Formation and Evolution in Massive Protoclusters with Blue Profiles (ASSEMBLE): Core Growth, Cluster Contraction, and Primordial Mass Segregation
Fengwei Xu, Ke Wang, Tie Liu +40
The ALMA Survey of Star Formation and Evolution in Massive Protoclusters with Blue Profiles (ASSEMBLE) aims to investigate the process of mass assembly and its connection to high-m…
Photochemical origin of SiC in the circumstellar envelope of carbon-rich AGB stars revealed by ALMA
Yanan Feng, Xiaohu Li, Tom J. Millar +16
Whether SiC is a parent species, that is formed in the photosphere or as a by-product of high-temperature dust formation, or a daughter species, formed in a chemistry driven by…
Direct observational evidence of the multi-scale, dynamical mass accretion toward a high-mass star forming hub-filament system
Dongting Yang, Hong-Li Liu, Anandmayee Tej +28
There is growing evidence that high-mass star formation and hub-filament systems (HFS) are intricately linked. The gas kinematics along the filaments and the forming high-mass star…
Evidence of high-mass star formation through multi-scale mass accretion in hub-filament-system clouds
Hong-Li Liu, Anandmayee Tej, Tie Liu +30
We present a statistical study of a sample of 17 hub-filament-system (HFS) clouds of high-mass star formation using high-angular resolution (1-2 arcsecond) ALMA 1.3mm and 3mm…
ATOMS: ALMA Three-millimeter Observations of Massive Star-forming regions -XIV. Properties of resolved UC Hii regions
C. Zhang, Feng-Yao Zhu, Tie Liu +15
Hydrogen recombination lines (RRLs) are one of the major diagnostics of the physical properties of H{\sc ii} regions. We use RRL H40, He40 and 3 mm continuum emission to inve…
ATOMS: ALMA Three-millimeter Observations of Massive Star-forming regions -- XII: Fragmentation and multi-scale gas kinematics in protoclusters G12.42+0.50 and G19.88-0.53
