摘要：

An optical polarization map of NGC 3125 shows that it is, in part, a large-scale bipolar reflection nebula illuminated from within the central starburst region. The dust appears to be asymmetrically distributed throughout the galaxy, and we propose that the dust has been formed in the starburst region and transported into the outer parts of the galaxy entrained in an episodic galactic wind. We estimate the mass of dust giving rise to the reflection nebula to be similar to 4 x 10(5) M(circle dot) which is significantly more than that detected via IR emission in the 'warmer' starburst region.
