Turning out the Light: A WFC3 Program to Image z>2 Damped Lyman Alpha Systems

Turning out the Light: A WFC3 Program to Image z>2 Damped Lyman Alpha Systems We propose to directly image the star-forming regions of z>2 damped Lya systems (DLAs) using the WFC3/UVIS camera on the Hubble Space Telescope. In contrast to all previous attempts to detect the galaxies giving rise to high redshift DLAs, we will use a novel technique that completely removes the glare of the background quasar. Specifically, we will target quasar sightlines with multiple DLAs and use the higher redshift DLA as a ``blocking filter'' (via Lyman limit absorption) to eliminate all FUV emission from the quasar. This will allow us to carry out a deep search for FUV emission from the lower redshift DLA, shortward of the Lyman limit of the higher redshift absorber. The unique filter set and high spatial resolution afforded by WFC3/UVIS will then enable us to directly image the lower redshift DLA and thus estimate its size, star-formation rate and impact parameter from the QSO sightline. We propose to observe a sample of 20 sightlines, selected primarily from the SDSS database, requiring a total of 40 HST orbits. The observations will allow us to determine the first FUV luminosity function of high redshift DLA galaxies and to correlate the DLA galaxy properties with the ISM characteristics inferred from standard absorption-line analysis to significantly improve our understanding of the general DLA population.

We propose to obtain WFC3 images through various filters of galaxies responsible for damped Lyman alpha absorption observed in SDSS spectra of high redshift quasars. We have a total of 20 candidate galaxy sightlines, each allocated 2 orbits, for a total of 40 orbits in the program. Each galaxy is assigned its own visit spanning 2 orbits. All exposures within a particular visit are taken with the same WFC3 filter. Each visit is dithered using the WFC-UVIS-DITHER-BOX pattern, with a CRSPLIT at each pointing, giving a total of 8 exposures per visit, with each exposure lasting between 600 and 800 seconds. The exposures all use the UVIS1 aperture, so as to remove any possibility that the candidate galaxy lies on the inter-chip gap. The exact position of the galaxy is not known, but will lie within a few arcseconds of the coordinates given, which are the SDSS coordinates of the background QSO. It should be noted that due to high redshift absortion, the QSO flux will be zero in the bandpass of the filter chosen in the observation, so any bright object concerns from the QSO itself are negated.
