Applying the Velocity Gradient Technique in NGC 1333: Comparison with Dust Polarization Observations
Published 2024-01-01“…Specifically, we use the VGT on molecular line data toward the NGC 1333 star-forming region ( ^12 CO, ^13 CO, C ^18 O, and N _2 H ^+ ), and we compare the derived B -field properties with those inferred from 214 and 850 μ m dust polarization observations of the region using Stratospheric Observatory for Infrared Astronomy/High-Resolution Airborne Wide-band Camera Plus and James Clerk Maxwell Telescope/POL-2, respectively. We estimate both the inclination angle and the 3D Alfvénic Mach number M _A from the molecular line gradients. …”

B-fields and Dust in Interstellar Filaments Using Dust Polarization (BALLAD-POL). IV. Grain Alignment Mechanisms in the Cocoon Nebula (IC 5146) Using Polarization Observations from...
Published 2025-01-01“…In this work, we investigate the grain alignment mechanisms in the F13 (F13N and F13C) and F13S filamentary regions of the Cocoon Nebula (IC 5146) using observations of polarized thermal dust emission from James Clerk Maxwell Telescope/POL-2 at 850 μ m. We find that the polarization fraction decreases with increasing total intensity and gas column density in each region, termed a polarization hole. …”
