Query: Ultraviolet HST Snapshot Survey of 3CR Radio Source Counterparts at Low
  Redshift   We present ultraviolet images of 27 3CR radio galaxies with redshifts z<0.1
that have been imaged with the Space Telescope Imaging Spectrograph (STIS) on
board the Hubble Space Telescope (HST). The observations employed the NUV-MAMA
and broad-band filters with peak sensitivity at 2200A . We find that the UV
luminosities show approximately a factor of 10 to 100 higher dispersion than
the optical. We compare the UV morphologies with optical V- and R-band WFPC2
snapshot survey images. We have found dramatic, complex and extended
ultraviolet emission from radio galaxies even at zero redshift. We find a
diverse range of UV morphologies, some completely divergent from their visual
morphology, which are reminiscent of the chaotic high-z radio galaxies
structures seen in rest-frame UV. The UV morphologies show regions of star
formation, jets, and possible scattered AGN continuum. The UV emission is
generally not aligned with the radio structure. We also detect the diffuse UV
emission of the host galaxy. We propose that these are the same physical
phenomena as observed at high redshift, but on a smaller spatial scale.
