A clump population framework for star formation across galactic scales
J. W. Zhou, Sami Dib, Tie Liu +11
Whether star formation across different spatial scales and galactic environments follows universal laws remains poorly understood. We investigate cloud-scale star formation in 30 d…
Automated void identification by Blendmask: from hierarchical molecular gas to hierarchical voids in NGC 628
J. W. Zhou, A. A. Han
We identify voids in NGC 628 from the JWST MIRI F770W image using a deep_learning method (BlendMask) and refine them by intensity contrast. These voids may be feedback_driven bubbl…
High-resolution APEX/LAsMA CO and CO (3-2) observation of the G333 giant molecular cloud complex : III. Decomposition of molecular clouds into multi-scale hub-filament structures
J. W. Zhou, J. S. Urquhart, F. Wyrowski +3
We decomposed the G333 complex and the G331 giant molecular cloud into multi-scale hub-filament systems (HFs) using the high-resolution CO (32) data from LAsMA observatio…
Self-similar cluster structures in massive star-forming regions: Isolated evolution from clumps to embedded clusters
J. W. Zhou, Pavel Kroupa, Sami Dib
We used the dendrogram algorithm to decompose the surface density distributions of stars into hierarchical structures. These structures were tied to the multiscale structures of st…
Gas inflows from cloud to core scales in G332.83-0.55: Hierarchical hub-filament structures and tide-regulated gravitational collapse
J. W. Zhou, S. Dib, M. Juvela +4
The massive star-forming region G332.83-0.55 contains at least two levels of hub-filament structures. The hub-filament structures may form through the "gravitational focusing" proc…
Feedback from protoclusters does not significantly change the kinematic properties of the embedded dense gas structures
J. W. Zhou, S. Dib, F. Wyrowski +11
A total of 64 ATOMS sources at different evolutionary stages were selected to investigate the kinematics and dynamics of gas structures under feedback. We identified dense gas stru…
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…
High-resolution APEX/LAsMA CO and CO (3-2) observation of the G333 giant molecular cloud complex : II. Survival and gravitational collapse of dense gas structures under feedback
J. W. Zhou, F. Wyrowski, S. Neupane +4
We investigate the physical properties of gas structures under feedback in the G333 complex using data of the 13CO (3-2) line in the LAsMA observation. We used the Dendrogram algor…
High-resolution APEX/LAsMA CO and CO (3-2) observation of the G333 giant molecular cloud complex : I. Evidence for gravitational acceleration in hub-filament systems
J. W. Zhou, F. Wyrowski, S. Neupane +6
Hub-filament systems are suggested to be the birth cradles of high-mass stars and clusters. We apply the FILFINDER algorithm to the integrated intensity maps of the 13CO (3-2) line…
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…
