Abstract Spectropolarimetry of the narrow line radio galaxy 3C234 was used to show in 1982 that there is a hidden broad line region occulted by an opaque torus orien- ted perpendicular to the radio structure axis. Given the luminosity of the re- flected light, we know that 3C234 would be called a quasar if its orientation with respect to the line of sight were different. Since then similar results were found for NGC1068 and 8 other Seyferts 2s, and for several other N.L.R.G.s. If many NLRG's are occulted quasars in the sky plane, several statistical anomo- lies in the beam model for superluminal motion are understandable. However, fur- thur optical spectropolarimetry has been disappointing in this regard, appa- rently because of severe dilution of reflected light by starlight, sometimes po- larized, from the host galaxies. We can solve this problem by observing in the UV. Furthermore recent observations of several NLRGs have revealed OFF-NUCLEAR dust clouds reflecting and strongly "bluening" nuclear light. Such dust clouds, abundant in the merger debris surrounding many luminous radio galaxies, should show up spectacularly in UV polarization images, providing information on the beam pattern and time history of nuclear emission. We request FOC polarization images of a sample of radio galaxies, including two with bright blue off-nuclear patches found by Dey and van Breugel. We will also get for free and with high efficiency total flux images, suitable for studying the nuclei and anomalous young stellar populations seen in merging radio galaxies from the ground. ------------------------------------------------------------------------------------ ------------------------------------------------------------------------------------ 9.

Description of proposed observations. For each object we would like a series of FOC polarization images using F/96 and F320W, taking exposures with Pol0, Pol60, and Pol120 all GROUPed together and taken at the SAME ORIENT. Total exposure on each target is 30 minutes, with 10 minutes on each polarizer position angle. ------------------------------------------------------------------------------------ 11.
