5. Abstract

We propose deep far-UV imaging of the Hubble Deep Field (HDF) with the ACS-SBC .
Previously, we surveyed 1/5 of the HDF in the UV and now propose to complete the
area. Near- and far-UV number counts suggest that there is a large population of UV-
bright starbursts at moderate redshifts (z<0.6), and our proposed observations will
investigate their nature. We will measure the star formation properties of these
galaxies and their morphologies in the UV, optical, and near-IR. This catalog of
starbursts will also be important to the astronomical community after Cycle 11 in
interpreting planned SIRTF observations of the field. We will also set strict limits
on the flux escaping in intermediate redshift (1<z<2) galaxies at wavelengths below
the rest-frame 912 Angstrom Lyman limit, and thus infer the contribution of star
forming galaxies at z~ 5 to the metagalactic ionizing radiation. Finally, we will
measure the diffuse far-UV background at 1600 Angstrom. The HDF is the best field in
the sky for the background measurements, given the legacy of ultra-deep observations
at other wavelengths. In the spirit of the Hubble Deep Fields, we waive proprietary
rights to these data.

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

     We propose to observe the remaining areas of the HDF that were not covered by
     GO-7410. We will observe a total of 14 ACS/SBC fields of view, for two orbits
     each, in the SBC+F150LP mode (the F150LP has lower background than F140LP in
     the CVZ observations; Brown et al. 2000). The low sky background and dark
     count, coupled with the absence of read noise, means that ACS can detect
     galaxies in the far-UV more efficiently than WFPC2 (F160BW), despite the small
     field of view (31 arcsec * 35 arcsec). Similarly, the higher throughput and
     larger field of view give ACS/SBC an advantage for this program over the STIS-
     MAMA, despite the latter's lower dark current. Our signal to noise estimates
     are based on the observations of GO-7410, scaled to the ACS-SBC instrument
     characteristics and our proposed exposure time. Our goal is to obtain a sample
     of starburst galaxies complete to FUV_AB = 27 mag. That is the magnitude at
     which the large number of bright starbursts in the number counts deviate
     strongly from the baseline model predictions. The previous (STIS) program
     reached a 5Sigma limiting magnitude (~ 90% completeness) of FUV_AB ~ 27.4 in
     the highest dark current regions of that detector. Thus with 1/2 the exposure
     time and the superior throughput of ACS/SBC, we can be confident that our
     sample will detect all FUV_AB < 27 galaxies. Our total orbit request is thus 14
     fields, with 2 CVZ orbits per field in the ACS/SBC-F150LP.

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

     CVZ is assumed in our orbit request. The HDF was chosen to take maximum
     advantage of the CVZ and so this program is a natural use of valuable CVZ time.
     In the spirit of the HDF, we waive all proprietary rights to these data.
