abstract:

    line_1:        The purpose of this program is to locate and obtain spectra of several primeval
    line_2:        galaxies (i.e., galaxies at very high redshifts). The method employed is to
    line_3:        obtain deep WF/PC exposures of the regions near known high redshift quasars and
    line_4:        search for faint, extended objects, including anything associated with the
    line_5:        quasars themselves. Out of the three WF/PC fields, the three brightest extended
    line_6:        objects will be chosen for follow-up with the FOS. Depending on the magnitudes
    line_7:        of the objects, long integrations with G650L or the prism will be used to
    line_8:        compare the spectral energy distributions of the primeval galaxies to lower
    line_9:        redshift objects to study the evolution of galaxies.

  question:        3
    section:       1
    line_1:        WFPC2 exposures with the F606W filter of ~7.9 ks duration are requested for
    line_2:        three of the highest redshift quasars known. These images will be searched for
    line_3:        signs of extended emission which may either be associated with the quasar
    line_4:        itself or with neighboring galaxies. Because the region in the immediate
    line_5:        vicinity of the quasar is of interest, the Baum spot will not be used. With
    line_6:        the wide filter, the roughly 18th magnitude quasars will saturate during the
    line_7:        long exposures and bleed down a column or two on the CCD. This is preferable
    line_8:        to losing the entire region immediately adjacent to the quasar.
    line_10:       Assuming that at least several extended objects are found, the three brightest
    line_11:       candidates will be observed with FOS, using either G650L (if V </~ 24) or the
    line_12:       prism (24 </~ V </~ 26). Acquisition will be either by peak-down on the QSO
    line_13:       with the 2.0_BAR aperture or by blind offset from the quasar,
    line_14:       using the WFPC2 image to derive accurate offsets (depending on whether the fuzz
    line_15:       is directly associated with or adjacent to the QSO). If no FOS targets are
    line_16:       identified, the time will be rescheduled to other FOS projects.
    line_17:       Cycle 9 16.26 hours primary, 0 hours parallel

  question:        5
    section:       1
    line_1:        The SV prerequisite programs for all FOS observations in this
    line_2:        program are:
    line_3:        Prop ID 2195 FOS Target Acquisition Tests All observations
    line_4:        Prop ID 1317 Int./Ext. Wavelength Offsets 1st target
    line_5:        Prop ID 1318 Spectral Flat Fields 1st target
    line_6:        Prop ID 1320 Absolute Spectrophotometry 1st visit of
    line_7:        bright targets
    line_8:        For those programs performing polarimetry, all include the following:
    line_9:        Prop ID 1430 Polarimetric Calibration All observations

!

  question:        12
    section:       1
    line_1:        Because of the somewhat speculative nature of this project, it does not become
    line_2:        a viable scientific investigation until all of the FOS data are in hand. No
    line_3:        data should be made public until at least one year after this time.

!

  question:        13
    section:       1
    line_1:        The purpose of this program is to search the region directly adjacent to high
    line_2:        reshift quasars for faint extended emission associated with the quasar or
    line_3:        nearby extended objects which are assumed to be primeval galaxies. FOS spectra
    line_4:        of the three brightest of any such objects detected will be used in comparison
    line_5:        to spectra of lower redshift objects to investigate galaxy evolution.
