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…
