Improvement in resolution and sensitivity from SMA subcompact (left, resolution of 2”) to SMA extended (middle, resolution of 0.7”) to ALMA (resolution of 0.26”) towards the high-mass star-forming cores W51 e2 (top) and W51 e8 (bottom). Contours are dust continuum. Red segments indicate magnetic field orientations measured from dust polarization in Band 6 (220 GHz) with ALMA and at 345 GHz with the SMA (Koch et al. 2018, ApJ, 855, 39).

Left Figure: SMA dust continuum observation at 345 GHz of the star-forming core W51 e2 with a resolution of about 0.7 arcsec. The color-wedge indicates the dust emission intensity. The measured magnetic field morphology (white segments), shows that gravity is bending the field lines almost radially and pulling them toward the core center. Overlaid in blue are the intensity gradients of the dust emission. The correlation between field and intensity gradient orientations is used as a starting point in our method. Right Figure: Resulting field strength map for W51 e2. An increase in field strength toward the center is apparent.
A New Method for Magnetic Field Strength Maps for Molecular Clouds
SMA observational results of the dust continuum emission at wavelengths of 870 micron (color scales and contours) and the magnetic field projected in the plane of sky (shown in segments). The observed magnetic field orientations (red segments) on the ∼0.3 pc scale with the SMA subcompact configuration (SMA-SubC, color scale and cyan contours) shows some mirror-symmetry features from north to south. Here, the field lines might be channeling and aligning material from both north and south. At a∼60 mpc scale resolution observed with the SMA extended configuration (SMA-Ext), dense cores are, indeed, detected along the east–west mirror symmetry axis (black contours). Smooth changes in field morphologies (white segments) are found within individual cores, whereas large overall changes in position angles can occur in between the cores.
Dust continuum and polarization from envelope to cores in star formation: a case study in the W51 North region
Left: Contour plot of the antenna beam pattern measured in the far field. The units are in decibels. The cross-structure around the secondary sidelobes is likely to result from scattering of the secondary-mirror support structure. Right: One-dimensional scans, extracted from the left panel, parallel to the x- and y-axes after location of the main beam maximum. Overlaid is the simulation result for the E-plane at 95 GHz.
