Abstract We propose far-UV imaging of a sample of seven of the nearest powerful radio galaxies with the FOC. These data will provide qualitatively new insights into the radio galaxy phenomenon. They will: 1) Test the currently-fashionable 'unification schemes' for AGNs, by searching for light from a 'buried' quasar that has been scattered into our line-of-sight by dust or warm electrons in the radio galaxy's ISM 2) Probe the 'starburst-AGN-connection' and its role in fueling radio galaxies, by determining the structure and morphology of the regions of star-formation that have been glimpsed in existing ground-based optical images of some radio galaxies, and 3) Provide a local laboratory in which the mysterious 'alignment effect' that dominates the UV properties of high-redshift radio galaxies can be studied. Archival IUE spectra of our sample galaxies demonstrate that UV light will be detectable with HST. The UV imaging capabilities of HST are required for this project because scattered AGN light and light from young stars are both so blue that they would have at least a 30-times-better contrast against the old underlying stellar population at 2000A than at 3500A. The high angular resolution of HST is required for both the detection of this light and for the delineation of its structure. ------------------------------------------------------------------------------------ ------------------------------------------------------------------------------------ 9.

Smith NASA GODDARD SPACE FLIGHT CENTER USA ------------------------------------------------------------------------------------ 3. Description of proposed observations. We plan to obtain images of each of the five radio galaxies with the FOC in f/96, configured as a 512x512 pixel (11 x 11 arcsec) array (unzoomed). For each galaxy, we will obtain four exposures through the F210M filter, each having an exposure time of 1000sec. These four exposures will be added together, and since we do not know a priori that any single exposure will have a point source bright enough to use to align and coregister the four frames, we will need the four exposures to be taken at the same position and with the same orientation. For each galaxy we will also obtain a single exposure of 800sec duration through the F470M filter. This image will be used in conjunction with the corresponding F210M image set to contruct a color map of the galaxy. It is therefore important that this image be taken in the same position and orientation as the set of F210M images. Since we plan to restore these images (if a source of adequate surface brightness is detected), we require fine-lock to insure the highest quality Point -Spread-Function. Because we shall be coadding the multiple images, it is desirable that the exposures be obtained in a contiguous fashion. ------------------------------------------------------------------------------------ 6.
