Polarized broad HeI and Paschen lines in NGC 1068
Abstract
We present J-band spectropolarimetry of NGC 1068. We observe polarized broad Pa beta and, for the first time, polarized broad Pa gamma and HeI. Assuming electron scattering as the polarization mechanism, the polarized broad lines suffer little or no extinction. All the polarized broad lines are redshifted with respect to the narrow lines, attributed to an outflow velocity for the scatterers of 900 +/- 200 km s-1.
