A comparison of polarised dust emission and the cold gas kinematics. Top: the channel maps of [C II] emission in a velocity bin of 100 km s⁻¹. The white contours show the polarised dust emission as in Fig. 1. The white open ellipse in the bottom-left corner shows the final clean beam of the [C II] (0.25″ × 0.24″). The polarised dust emission mostly overlapped with the velocity component near ~−150 km s⁻¹, which indicates it may only associate with some particular velocity components. Bottom: the comparison of the spatial distribution between polarised dust with the total intensity, velocity and velocity dispersion of [C II]. The peak of the polarised dust emission comes closer to the peak of [C II] emission than the total dust emission, and it is co-spatial with the region with a shallow velocity gradient and relatively low-velocity dispersion.
