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.
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.
