The rare subclass of optically-selected QSOs known as low-ionization broad absorption line (LoBAL) QSOs show signs of high-velocity gas outflows and reddened continua indicative of dust obscuration. Recent studies show that galaxies hosting LoBAL QSOs tend to be ultraluminous infrared systems that are undergoing mergers, and that have dominant young (< 100 Myr) stellar populations. Such studies support the idea that LoBAL QSOs represent a short-lived phase early in the life of QSOs, when powerful AGN-driven winds are blowing away the dust and gas surrounding the QSO. If so, understanding LoBALs would be critical in the study of phenomena regulating black hole and galaxy evolution, such as AGN feedback and the early stages of nuclear accretion. These results, however, come from very small samples that may have serious selection biases. We are therefore taking a more aggressive approach by conducting a systematic multiwavelength study of a volume limited sample of LoBAL QSOs at 0.5 < z < 0.6 drawn from SDSS. We propose to image their host galaxies in two bands using WFC3/UVIS and WFC3/IR to study the morphologies for signs of recent tidal interactions and to map their interaction and star forming histories. We will thus determine whether LoBAL QSOs are truly exclusively found in young merging systems that are likely to be in the early stages of nuclear accretion.

We propose to obtain imaging observations of 22 LoBAL QSOs host galaxies using WFC3/UVIS with the F475W filter and WFC3/IR with the F125W filter. Each object will require a single orbit. In addition, we plan to spend one orbit observinng a PSF star with the same instrument configuration in order to construct a PSF model with a very high dynamic range. Therefore we request a total of 23 orbits. The observations in F475W will cover restframe ~2500 A to ~3600 A. This region is very sensitive to the age of the stellar populations, with young populations being significantly brighter than old populations. Balmer emission lines and [O II] 3727A will be excluded from this region even for the highest z objects in our sample. Normally, one would have to worry about MgII 2800A being included in this region. However, since these objects are LoBALs, the nuclear MgII emission is much less intense than in normal QSOs. Observations in F125W will cover restframe ~6900 to ~9300A, a region dominated by the continuum from older stellar populations. This region excludes H-alpha from even our highest z targets. These observations are particularly helpful to search for tidal tails and debris, and to determine the morphological types of the hosts. The ratio of both images will map stellar populations and our Spitzer observations will help us quantify the star formation. Using both the morphological information and the color maps, we can recreate merging and star forming histories for these objects (see Canalizo & Stockton 2000 for a description of the technique). An obvious concern is the possibility of dust obscuration in the host galaxies, which could potentially confuse the results inferred from the color maps. We will obtain follow up Keck spectroscopy for those objects where there is ambiguity, in order to quantify the redenning and to verify the inferred stellar populations in any extended features that we find. Our targets are visible for 54 - 58 minutes per orbit, depending on their declination. For each target, we will need six minutes for guide star acquisition. Next, we will obtain two exposures 800s to 900s each (depending on the visibility of the target) with WFC3/UVIS using the F475W filter, for a total exposure time of 1600s to 1800s. This will give us a S/N of ~5 per kpc^2 (or 0.2 arcsec^{-2}) assuming a flux of 5 x 10^{-19} ergs cm^{-2} s^{-1} A^{-1} arcsec^{-2} for the host galaxies. This value is a conservative estimation based on our Keck ESI spectra of the host galaxies of other QSOs at $z\sim0.5$. However, for regions with young stellar populations, we will achieve higher signal to noise. Next, we will switch to WFC3/IR while the last buffer dump is occuring. We will then take a two-dither pattern with 500s exposures in the F125W filter, for a total of 1000s of integration time. This will give us a S/N~12 using similar assumptions as above. The total time needed, including overheads, will be 54 - 58 minutes, so that each object can be observed in only one orbit. We propose to spend one orbit to obtain a deep, unsaturated stellar PSF using both the F475W and F125W filters with a star centered on exactly the same part of the chip as all the science objects. We will obtain images of the white dwarf GRW+70D5824. This star was chosen as its B-V color of 0.09 is comparable to the average color of our QSO sample. To avoid contamination of the PSF by scattering of another nearby bright object, we carefully checked that no bright star lies within 30 arcsec. We will carry out five exposures of different lengths at two dither positions. The 2-point dither pattern will improve the sampling of the PSF. The three exposures with lengths of 4 s, 40 s and 400 s will insure that we obtain both unsaturated images of the PSF core and deep images of the wings. From that, a composite PSF of very high dynamic range will be created. Our program is best suited for WFC3 because of the possibility of taking the optical and IR images with the same instrument. However, if WFC3 is not available for Cycle 17, the observations can easily be switched to ACS WFC and/or NICMOS if necessary.
