The currently observed clumps cannot be the "direct" precursors of the currently observed open clusters

J. W. Zhou, Sami Dib, Pavel Kroupa

We categorized clumps, embedded clusters, and open clusters and conducted a comparative analysis of their physical properties. Overall, the radii of open clusters are significantly…

Molecular clouds as hubs in spiral galaxies : gas inflow and evolutionary sequence

J. W. Zhou, Sami Dib, Timothy A. Davis

We decomposed the molecular gas in the spiral galaxy NGC 628 (M74) into multi-scale hub-filament structures using the CO (2-1) line by the dendrogram algorithm. All leaf structures…

The star formation histories, star formation efficiencies and ionizing sources of ATLASGAL clumps with HII regions

J. W. Zhou, Sami Dib, Pavel Kroupa

1226 ATLASGAL clumps with HII regions were matched with radio sources in the CORNISH-North/South surveys, and 392 of them have corresponding radio sources. We determined the stella…

Physical properties of embedded clusters in ATLASGAL clumps with HII regions

J. W. Zhou, Pavel Kroupa, Sami Dib

Using the optimal sampling model, we synthesized the embedded clusters of ATLASGAL clumps with HII regions (HII-clumps). The 0.1 Myr isochrone was used to estimate the bolometric l…

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…
