Local velocity gradients inside sub-parsec supercritical filaments are randomly oriented and uncorrelated with gravity, implying turbulence dominates small-scale gas dynamics near star formation.
Serendipitous discovery of a bound nine-member protostellar system in NGC 6334-43 formed by filament fragmentation, with outflows from two sources and virial masses derived for three cores.
Blue-asymmetric spectral lines appear in 50-60% of dense cores within massive dark clumps, showing that gravitational collapse operates at core scales from prestellar stages onward and supports hierarchical star formation.
ALMA comparison finds starless cores in evolved IRBCs have ~2x higher median mass and density than in early IRDCs, favoring competitive accretion over massive prestellar core models for high-mass star formation.
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.
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.
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.
