5. Abstract

Host galaxies of high-redshift, powerful radio sources are likely the progenitors of
present-day gE and cD galaxies, and therefore provide important laboratories in
which to investigate the formation of massive galaxies in the early Universe. At
z~gt 2, many high-redshift radio galaxies (HzRGs) exhibit giant, (~ 100 kpc-size) Ly
-alpha\ halos; similar nebulae without associated radio sources have recently been
discovered in a galaxy overdensity at z = 3.09 (Steidel et al.\ 1999). The LyAlpha
luminosity of these halos (~ 10^44 erg\ s^-1) is comparable to the total X-ray
luminosities of low--z X--ray clusters, and may reflect the hot, cooling gas
reservoir from which the galaxy/cluster is forming. Although these halos are easily
observable in z~gt 2 HzRGs (LyAlpha is redshifted into the optical window), their
redshift evolution has not yet been studied, primarily because the LyAlpha emission
in the z<1.8 galaxies lies at UV wavelengths inaccessible to ground-based
telescopes. We propose to use STIS on HST to search for Ly-alpha\ halos around giant
radio galaxies and in rich cluster environments at z ~ 1. This will test both their
redshift evolution (are they unique to the youngest phases of galaxy formation?) and
their association with dense cluster environments.

  Observations Description
  ------------------------

     The STIS prism throughput permits sensitive Ly-alpha detections for 0.6<z<1.5.
     We have therefore selected 8 targets: 5 radio galaxy targets from the z~1 3CR
     subsample which we have studied in great detail with HST and a wide variety of
     ground--based telescopes and 3 of the highest redshift X--ray emitting galaxy
     clusters known (two z~0.8 EMSS clusters and one at z=1.27 from Rosati et al.
     1999). We have wide--field IR and optical imaging for nearly all of our
     targets: three (3C265, 3C210, 3C324) are in moderately rich clusters, while two
     others (3C267, 3C266) appear to be in only modest groups or relatively
     isolated. We have NICMOS Camera 2 images of all the galaxies, and wide--field
     Camera 3 images of the environments for 3C210, 3C324, and 3C267. We also have
     WFPC2 polarimetry for 3C265, 3C266 and 3C324, which will enable the diagnostic
     studies described above. Objective-Prism Spectroscopy: The HST aperture is
     small compared to that of the 4m telescopes that have been used for LyAlpha
     imaging at z~3, but the (1+z)^4 Tolman scaling boosts surface brightnesses by a
     factor of 16 at z=1 relative to z=3. The extremely dark UV sky background and
     absence of readout noise in the STIS MAMAs also enhance our sensitivity to low
     surface--brightness emission, and Ly- alpha images with depth comparable to
     those of z~3 objects can be taken in a few orbits, with much higher spatial
     resolution. The dispersion of the STIS NUV--MAMA prism mode for Ly-alpha at z=1
     corresponds to a velocity resolution of ~ 3000kms/pixel, sufficiently low that
     even with the high velocities sometimes seen in radio galaxies, the prism--
     dispersed Ly-alpha will essentially form a monochromatic emission line image,
     with the faint galaxy continuum dispersed beneath it. For 3C 324 we have WFPC2
     LRF narrow band images taken in the OII3727 line, and know that the high
     surface brightness forbidden line emission is closely coincident with the UV
     continuum emission. In order to simulate an observation of Ly-alpha from these
     high surface brightness regions, we have taken the flux calibrated LRF image of
     3C 324 and scaled it to Ly-alpha using the `canonical' radio galaxy Ly-
     alpha/OII flux ratio (~8.5) derived by McCarthy 1993. We sampled this at the
     pixel resolution of the STIS NUV-MAMA prism mode, and computed the expected
     count rate using the total throughput at (1+z)*1216A derived from IRAF synphot.
     We then simulated a four--orbit exposure including the nominal NUV--MAMA dark
     count rate (the only significant source of background) and Poisson noise from
     the source. This image is shown in figure 1, and is a pessimistic estimate of
     the expected S/N because it also includes the noise from the original source
     data (the LRF OII image). The morphology of the (simulated) Ly-alpha emission
     is readily visible, demonstrating that a 4--orbit exposure should adequately
     map the high surface brightness Ly-alpha emission if it has roughly the
     canonical flux ratio with OII. We have also simulated a Ly-alpha halo using a
     King model profile fit to our flux--calibrated KPNO 4m narrow band Ly-alpha
     images of the halo around z = 3.395 radio galaxy B2 0902+034 (see Spinrad
     1987). The model halo was then de-- redshifted to z = 1.2 accounting for the
     (1+z)^4 surface brightness boost and the change in angular diameter distance.
     The expected NUV-MAMA prism count rate was computed and a 4-- orbit image
     simulated as described above. We then measured surface photometry from the
     simulated image in circular annuli: the resulting profile is shown in figure 2.
     Although the signal to noise per pixel is extremely low outside the halo center
     (as is also the case for the existing ground--based observations at z = 3.4), a
     simulated halo is readily detected in the azimuthally averaged profiles. Low--
     order spatial variations in the dark current may set the lower surface
     brightness limit at which we can measure a putative halo. In our experience
     with STIS NUVMAMA observations in the HDF--N and HDF--S (MD co-I on both
     projects) we achieved excellent dark subtraction, but the dark is temperature
     dependent and we cannot be certain how well we will do for the radio galaxies.
     Using 4 orbits for 3C 324 as a guideline, we have scaled exposure times for the
     other radio galaxies taking into account (1) (1+z)^4 dimming, (2) STIS
     throughput vs. Ly-alpha wavelength, and (3) foreground galactic extinction from
     Burstein & Heiles (1982). Imaging : A short image is part of the standard
     procedure when taking slitless spectroscopic images. Although it is not
     essential here for calibrating wavelengths in the slitless spectrogram since we
     are essentially using the prism mode as a narrow band imager, we include short
     F25QTZ imaging exposures nonetheless in order to get a direct map of the
     combined continuum+Ly-alpha flux over the radio galaxy image. Used together
     with the flux calibrated prism Ly-alpha` ``image,'' we will derive a
     measurement of the UV continuum luminosity of the radio galaxy in a broad
     bandpass centered roughly on Ly-alpha. This has never been done for z ~ 1 radio
     galaxies, and will further facilitate comparison to z > 2 objects (where the UV
     continuum is observed directly from the ground). It will also permit an
     approximate measure of the Ly-alpha equivalent width, averaged over the galaxy
     and perhaps for individual regions within the image. Observing Methodology: For
     each target, we will obtain an image of the target with the STIS CCD, an image
     of a narrow slit with the STIS CCD, an image of the target with the STIS MAMAs,
     and a short image with the 6x6 aperture on the STIS MAMAs. This imaging set up
     is necessary in order to unambiguously associate each part of the two
     dimensional spectrum with the UV image of the object. In addition, the images
     with the MAMAs will provide the first UV imaging of these targets. After the
     imaging, we will spend the rest of the time in each visit obtaining the
     slitless prism spectrum of the target.

  Real Time Justification
  -----------------------


  Calibration Justification
  -------------------------

     We are obtaining an image of the 52x0.05" slit with the CCD, and a short image
     of the 6x6" aperture with the NUV-MAMA to unambiguously map the aperture plane
     to the sky and detector coordinates (for each move of the Mode Selection
     Mechanism).
