Radio observations show gas in Mon R2 flows from inter-filament regions into filaments and the central hub, with along-filament accretion rates 6.8 times cross-filament rates in filaments and 1.5 times in inter-filament gas.
The highest mass stars (>100 M _ ) form only in hubs

Magnetic fields remain aligned with projected gravity throughout the DR21 ridge and sub-filaments, indicating guided accretion at rates that can build the ridge in about one million years.
Deep learning identifies voids in NGC 628 with low association to known star clusters, supporting an evolutionary sequence from molecular clouds via stellar feedback to detached voids.
Oblique filament collisions lead to gravitational collapse of the compressed cloud when post-collision |gravitational energy| exceeds kinetic plus thermal plus magnetic energies, with lower angles and lower velocities favoring hub-filament formation.
Multi-wavelength observations identify a compact hub-filament system in G286.21+0.17 whose core properties follow steep radial power laws consistent with competitive accretion.
Young star clusters in the NGC 628 simulation inherit a filament mass power-law index of -1.35 at formation via gravitational fragmentation and evolve to -1.55 after 60 Myr.
Synthetic Herschel observations from simulations yield 8832 filaments hosting 94% of clumps, with power-law mass and length distributions and a density relation qualitatively matching the Hi-GAL survey.
New observations confirm hourglass magnetic fields at clump scales in G35.20-0.74, with strengths of approximately 600 μG in G35N and 850 μG in G35S, supporting magnetically regulated collapse in G35N and feedback influence in G35S.
