5. Abstract

We propose to determine whether high luminosity galaxies selected using rest
ultraviolet luminosity at low-to-moderate redshift (0.2<z<0.7; UV-selected Bright
Galaxies UBG) are related to Lyman-break galaxies (LBGs) at high redshift (3<z<5)
selected by the drop-out technique. Each arise in flux-limited samples selected at
rest Lambda~ 1500Angstrom. This is the first effort to make a systematic comparison
of the high z population to a similar luminosity class of galaxies at moderate
redshift also selected in a flux-limited photometric survey at the same rest
wavelength. Study of these analogs will provide a critical baseline for high z
survey interpretation. Our objective is to answer the following questions: 1. What
is the star formation rate in UBGs, the extinction correction, and how do these
compare with the LBGs? 2. What is the morphology and size of the UBGs, and how does
this compare with that of the LBGs? 3. Do the UBGs show evidence for prior episodes
of star format io n, how does this compare to the prior star formation in the LBGs,
and how is this older population distributed? 4. Do the UBGs show spectra similar to
that of the high z sample? 5. Are the UBGs analogs to LBGs? Ultimately, our
objective is to test hierarchical structure models for galaxy formation and
evolution. We also propose test whether the Lyman continuum flux escapes the
galaxies.

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

     Rationale for Target Selection The FOCA UBGs are a unique galaxy sample, the
     only high SFR, moderate redshift objects selected in a blank-sky, vacuum UV
     survey by a technique essentially identical to optical magnitude-limited
     selection of high z objects. Their star formation rates are comparable to the
     LBGs. Extensive ground-based observations at Palomar and Keck have already been
     performed, including photometry, moderate and high resolution spectroscopy. We
     plan further multi-slit observations to determine the local galaxy density
     around each UBG. We are proposing to observe the field at the VLA in 20 cm and
     6 cm in order to use the radio continuum-Far IR correlation citehelou85 to
     certify and calibrate the spectral-slope/extinction technique for this class of
     objects. In Table 1 we list the basic information about our proposed targets,
     including estimated SFR and SFR/area assuming that the galaxies exhibit the
     mean extinction of local starbursts citemeurer95. The targets a re the highest
     redshifts objects in the FOCA/NORRIS sample, and all have had Keck LRIS
     spectroscopy (and some Keck HIRES). HST is clearly required for these reasons:
     (1) the UV properties are fundamental to our investigations, and only with HST
     can we obtain the necessary spatially resolved UV photometry that will allow us
     to extract local and global extinction and starburst age; (2) the local and
     global morphology and structure of the starburst regions cannot be resolved on
     the ground, yet is a key discriminant among physical starburst models.

     capabilities of the STIS MAMA and the high surface brightness of the starbursts
     that we target make these observations possible with only modest exposures.
     Meuer et al. (1995; citemeurer95) have already shown that even with the pre-
     COSTAR system, the FOC could obtain good quality images of local starbursts at
     2200Angstrom\ with short exposures. The improved FUV capabilities of the STIS
     MAMA over the FOC and the aberration correction more than make up for the
     moderate Tolman dimming of these objects, if they exhibit the same UV surface
     brightness as local starbursts, even allowing us to map surface brightnesses
     <10\ the average local starburst in moderate exposures. Table 2 sho ws
     estimated countrates for the NUV MAMA with the QUARTZ filter, the FUV MAMA with
     the SrF_2 filter, and the CCD with the long-pass filter, along with the total
     detector, geocoronal, and earthshine background. We assume shadow for the FUV
     MAMA observations, and low zodiacal light for all (the ecliptic latitude is 50
     degrees). The countrate and S/N ratio has been calculated in (0.2 arcsec)^2
     pixels, corresponding roughly to 0.5-1 kpc^2 pixels at the galaxies (q_0=0.5,
     H_0=75), a 50*50 pixel image of the three large galaxies. We have total flux
     measurements at 2000Angstrom, central between the FUV and NUV MAMA bandpasses,
     and we assume based on the UV/optical colors a B3V stellar spectrum. We assume
     in all cases that the emission is either spread out over 50\ emission line
     distribution from Keck observations) or 10\ area (yielding surface brightnesses
     comparable to local starbursts citemeurer95), and morphologies similar to UV
     images of nearby galaxies. We also assume that there i s no flux below rest
     912Angstrom\ in each galaxy. We use sensitivity, sky and detector background
     data from the STIS Instrument Handbook, Ver. 1.0. The observations are
     basically photon-limited. We give in Table 2 the required exposures to achieve
     S/N=10 (FUV, NUV) or S/N=20 (CCD) in the 0.2*0.2 arcsec^2 pixels, along with
     the actual exposure times requested. These are net times after overhead is
     subtracted. Figure reffiggal shows a simulation using the HAlpha image of a
     nearby galaxy to illustrate the information content in such an image. Our
     measurement will derive the internal extinction (vs. position in the galaxy)
     from the ratio of the FUV and NUV flux. The error in the derived extinction is
     given by sigma(A_UV)=aSigma_Beta=2.2a(square)rtSNR_F^-2+SNR_N^-2, which for NUV
     SNR=10 and FUV SNR=10 and local starburst normalization citemeurer95 yields
     sigma(A_UV)=0.3. CCD observations will be taken as CRSPLIT=2. None of the
     fields violate any local or global MAMA countrate li mi ts. In the compact
     objects, the total number of counts in some bins could exceed the ACCUM 16 bit
     limit, so all MAMA images will be read out as a series of 2-4 exposures. We
     also propose to perform low resolution FUV spectroscopy on the two compact
     galaxies, 617 and 317. STIS with the FUV MAMA is ideal for searching for flux
     below the Lyman limit, since the objects redshift the Lyman continuum break to
     1500Angstrom\ and 1400Angstrom\ respectively, where the FUV MAMA and G140L
     sensitivity is rising rapidly towards shorter wavelengths. We have simulated a
     three orbit exposure of 617 in Figure reffigspec, using the galaxy spectral
     energy distributions of Charlot, Worthey, & Bressan citecharlot96, bruzual93,
     an 0.5 arcsec slit, using the instrument and background data from the STIS
     Handbook. We show four cases, corresponding to instantaneous bursts of age 2.6,
     6.6, 10, and 17 Myr. These give Lyman breaks of F_-912/F_+912=1, 0.3, 0.1, 0.02
     respectively. Even a decrement of 0.02 is easily detectable in the heavily
     binned spectrum (25Angstrom), giving source counts ~10\ the MAMA background
     counts. The other galaxy is slightly dimmer, but its slightly lower redshift
     gives it comparable counts and sensitivity. beginfiguretbp beginminipage2.7in

     targets. All targets are within 30 arcminutes of each other, but none are
     within 2 arcminutes. All are visible for 54 minutes. For FC089-498, orbit 1 is
     used: 9 min., guide star acquisition, 5 min., first science exposure of visit,
     25 min., 2 FUV MAMA exposures with 1 minute overhead per exposure in shadow.
     Orbits 2-4 have 6 min. reacquisition, 25 min. for 2 FUV MAMA exposures with 1
     min. overhead/exposure in shadow. Orbit 5 has a 6 min. reacquisition, a 18 min.
     NUV MAMA exposure (2 9 min.+2 min. overhead), a 5 min. change of detector and
     filter, 2 10 min. CCD exposures and 1 min. readout. Finally, orbits 5-6 have a
     6 min. reacquisition, a NUV MAMA 44 min. exposure split into 4 frames with 1
     min/frame overhead. For the spectroscopy targets, FC089-617, orbit 1, we have 6
     minutes for the reacquisition, 11 minutes for on-board target acquisition (no
     peak-up required), 5 minutes for the first spectroscopy exposure in the visit,
     and a 32 min ut e exposure. Orbit 2-3 has 6 min. for reacquisition, and a 48
     min. exposure. setlength -2pt setlength -2pt
