  In this study, we apply the Velocity Gradient Technique (VGT) to the merging
Centaurus galaxy. We compare gradient maps derived from the PHANGS-ALMA survey
using CO emission lines with magnetic field tracings from dust polarization
data obtained via the HAWC+ instrument. Our analysis reveals a strong
correspondence between the directions indicated by these two tracers across
most of the galactic image. Specifically, we identify jet regions as areas of
anti-alignment, consistent with previous reports that gradients tend to rotate
90 degrees in outflow regions. Statistically, we find that the alignment of
magnetic fields, as revealed by polarization, is most accurate in regions with
the highest signal-to-noise ratios. Our findings underscore the utility of
velocity gradients as a valuable complementary tool for probing magnetic fields
and dynamical processes in merging galaxies.
