Cosmic ray transport in molecular cloud simulations boosts star formation efficiency by up to 43% and yields a top-heavier IMF with a high-mass slope shallower by ~20%.
HONKAI identifies 193 dense cores in 16 clumps within three IRDCs, finding most have virial ratios >1 but mass-size relations below the massive star formation threshold and a steeper high-mass CMF slope.
The paper outlines the goals for the SKA-Mid Galactic Plane survey at 10-15 GHz to deliver the first uniform high-resolution view of ionized structures and feedback in the Milky Way.
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.
New CO(2-1) observations of 112 clumps in outer Galactic clouds (14-23 kpc) yield velocity dispersion-size and mass-size power laws plus a declining virial parameter trend indicating most clumps are gravitationally unbound.
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.
The paper presents a science case for using SKAO to probe jets, outflows, magnetic fields, dust, and chemistry in young stellar objects at scales of a few au.
