Abstract:                                ! Free format text (please update)
    We propose to continue our study of the continuum and Ly Alpha
    morphologies of 20 high--redshift radio galaxies begun in
    Cycle 5. Our sample was chosen from 50 candidates to be bright
    in both continuum and Ly Alpha. The observations would
    elucidate sub-kiloparsec-scale structures in the target
    galaxies, allowing study of their alignment and relationships
    to the associated radio sources.  Of particular interest is a
    comparison between the HST clumpiness and the recently
    discovered spatially-extended absorption systems in the Ly
    Alpha profiles., During Cycle 5 we were allocated time to
    begin the project, with 8 broad-band targets and 3 Ly Alpha
    LRF test images. The first of these observations show that (i)
    features of which are difficult to explain by a single simple
    scattering or starburst model, (ii) a variety of different
    morphologies, which provide compelling arguments that imaging
    a larger sample is essential for understanding the processes
    involved, (iii) our exposure times are well chosen to
    delineate the morphologies, both in the continuum and Ly
    Alpha. The images will also be used to provide the most
    interesting targets for a followup spectroscopic and kinematic
    study with STIS., The project is providing unique information
    relevant to the formation and evolution of radio galaxies, to
    relationships between galaxy and quasar activity and to
    physical conditions in the early Universe.

Questions                       ! Free format text (please update)

     Observing_Description:
         noindent Need for Extension of Sample. At the end of Cycle 5
         we will have imaged 8 objects in continuum and 3 in Ly Alpha.
         The diversity in morphologies coupled with the need to
         disentangle the many effects and various parameters discussed
         above provide compelling arguments for imaging a sizeable
         sample of distant radio galaxies with the HST, both in the
         continuum and in Ly Alpha. Imaging such a sample is also
         essential to make most efficient use of future HST time. Here
         we propose completing our sample of 20 objects in the
         continuum and 10 in Ly Alpha. Our proposed observations can
         be used to enable the most interesting targets to be selected
         for a followup spectroscopic and kinematic study with STIS
         and deep imaging with WFPC2, NIC and the AC. , , noindent
         Continuum Imaging. We shall carry out continuum imaging of 5 
         out of our
         sample of 20 radio galaxies known to have z > 2, R -
         magnitude < 23.5 and Ly Alpha fluxes > 10^  -15 erg s^  -1cm^  
         -2 . Two of the 5 targets have already been observed in Cycle 5

         but need deeper observations (5 and 6 orbits each respectively)

         and 3 of the targets are new and will be observed each for 2 
         orbits. Our choice of filter is dictated by three criteria.
         First bright lines (Ly Alpha) should be excluded from the
         pass band. Second, the filters should result in as large as
         possible detected light signal. Third, the rest-wavelengths
         should be as similar as possible over the redshift range. As
         a reasonable compromise between these criteria, we shall
         observe all z < 2.9 galaxies through F606W, the most
         efficient filter. For the z > 2.9 radio galaxies, Ly Alpha
         contamination will be avoided by observing through F702W.   ,
         * The PC is preferable as a detector than the WFC. Although
         the signal per pixel will be smaller for the PC, averaging
         the signal over 4.7 pixels should result in similar sampling
         to the WFC with very slightly degraded signal to noise.
         However, we regard the additional spatial resolution provided
         by the better sampling as a significant advantage. Our
         targets are all small compared with the field of the PC. , *
         We request an average of two orbits per target for the
         continuum imaging. First results of our Cycle 5 observations
         show that this exposure time for the broad-band imaging is
         sufficient to delineate the main features of the continuum
         morphologies. This choice was based on the following
         considerations. Our Cycle 1 (aberrated) exposures were each
         of length about 6 x 30m.  Both 4C 41.17 and 4C 28.58
         contained two or more 0.1" clumps, each of which produced
         more than 10\% of the total flux from these galaxies (less
         than 2.5 magnitudes fainter than the integrated galaxy
         magnitudes). Assume that all the targets have similar ratios
         of flux in clumpy structures and that we wish to observe
         galaxies down to integrated R-magnitudes < 23.5 (1.5
         magnitudes fainter than 4C 41.17). For a 40m minute exposure
         through the F606W filter with PC1, a 26th mag clump will
         produce 564 electrons per 0.1" by 0.1" PSF  (60\% of the
         energy is intercepted within this area). The resultant signal
         -to-noise per PSF after 2 orbits  is about 25. Most of the
         targets are 0.5 to 1.5 mag brighter than R = 23.5., ,  

   Real_Time_Justification:

          The project is part of a comprehensive study into the nature
         of distant galaxies, involving ground-based optical (incl.
         Keck), infrared and radio imaging and optical and IR
         spectroscopy. Our proposal builds on several years of
         preparatory ground-based programs. We have access to a huge
         body of relevant data including:, (i) optical images and
         spectra (Kitt Peak, La Silla, Tololo, Las Campanas, Lick, La
         Palma), (ii) Ly Alpha spectral profiles with a resolution of
         better than 100 km/s. , (iii) 2.2 micron images (UKIRT, Las
         Campanas), (iv) radio maps of the total intensity and
         polarisations at several frequencies and resolutions (VLA,
         MERLIN interferometric array at Jodrell Bank). (e.g. Carilli
         et al. 1995). These ground-based data (particularly
         comparable resolution radio maps) will be carefully compared
         with the HST data. Note that our HST images are comparable in
         resolution to the best VLA maps, For the first time they
         allow detailed comparisons between radio and optical
         morphologies to be made on the kiloparsec scale., (v) We have
         a large programme with ISO to search for dust in three of our
         proposed targets and we shall complement this with
         observations with the SCUBA sub-millimeter bolometer on the
         UK/NL JCMT., , Some of us have begun a programme to study the
         targets with the Keck Telescope and we intend to follow up
         the HST observations spectroscopically with Keck., , One of
         us (HR) is involved with WFPC2 observations of  a complete
         sample of  z~ 1 radio galaxies carried out during Cycle 4.
         (PI M. Longair). A "low-z" control sample will therefore be
         available to allow evolutionary effects to be studied., , Two
         of us are (WvB,GM) are involved with WFPC2 imaging of a
         similar sample of z > 2 quasars carried out during Cycles 4
         and 5. (PI M. Lehnert).
