Scientific paper

The authors have observed the linear polarization of 13 broad-line radio galaxies drawn from the list of Grandi and Osterbrock. Two of the objects, 3C 109 and 3C 234, are strongly polarized. As a class, these active galaxies display larger polarizations than both Seyfert 1 galaxies and quasars. The polarizations are attributed primarily to extinction and scattering by dust, though nonthermal components may contribute at a secondary level. The existence of dust affords a partial explanation for two of the spectral signatures of broad-line radio galaxies: steep Balmer decrements and strong forbidden lines relative to the permitted lines.
