Near-infrared polarization of the nucleus of M31.
Abstract
The nucleus of M31 is found to have zero polarization at wavelengths of 1.2, 1.6, and 2.2 microns. This suggests the absence of nonthermal infrared radiation and dust close to the nucleus, if it is assumed that the magnetic field has a constant direction in the observed region.
