Magnetic Fields in Massive Star-forming Regions (MagMaR). VII. On the dynamical importance of B-fields in massive protocluster W33 A

Published in Astronomy & Astrophysics, accepted, 2026

ALMA polarization observations of W33 A show how magnetic fields can stabilize filaments, regulate accretion, and delay core collapse within a single massive protocluster.
