NGC 3628 at H (1.65 microns). The polarization vectors have been averaged over a 2.7" beam. The longest vectors are about 2% polarization. The image is 70" wide and North is up.
NGC 3628 visual image with the H band polarization vectors overlayed. Note the dip in the contour of the dust lane where the polarization vectors depart from being aligned along the dust lane just SE of the nucleus.
