Our flash levels assume AVERAGE background. 206167204 ----- Attempting Submission 1 (Wed Jul 20 21:59:40 GMT 2016) ----- Our program coordinator advised us to ignore the warnings about the flash level. We understand that these arise only when LOW background is assumed, and we expect to have AVERAGE background for these observations. Confronting the 3D Orientation of Galactic Disks in Space: Disk Structure vs. Circumgalactic Gas Flows Can the origins of circumgalactic gas flows be recognized by their location relative to galactic disks? Several studies of disk galaxies paired with background quasars (or galaxies) at small angular separation suggest that the physical origin of halo absorption at low impact parameters (< 80 kpc) depends on azimuthal angle, i.e., the angular separation of the sightline from the major axis of the disk. We will use the spiral structure revealed by high-resolution, HST imaging to test the following paradigm: absorption near the galaxy major and minor axes arises, respectively, from gas accretion near the disk plane and winds blown perpendicular to the disk plane. Adopting this framework, we described the kinematics of circumgalactic Mg II absorption and established the required 3D orientation of ten galactic disks. These results, combined with rotation curves, predict the direction in which the spiral pattern in the disk wraps. We propose to resolve the spiral structure in HST images and thereby test the basic assumptions used by many researchers to interpret circumgalactic sightlines. The resulting knowledge will add interpretive value to the growing collection of archived, quasar spectra, which will hopefully elucidate how galaxies get their gas and enrich the surrounding medium with heavy elements. We aim to resolve spiral structure in ten galactic disks at intermediate redshifts. Imaging in two filters provides a large wavelength baseline and thereby optimizes contrast bewteen the underlying stellar disk (old stellar population) and spiral density waves (young stellar population). For galaxies at redshift 0.2, the F390W bandpass isolates ultraviolet blux shortward of 4000 Angstroms in the galaxy rest frame and will trace light from stars younger than roughly 100 Myr. The longer wavelength image in F814W will trace the older (> 1 Gyr) stellar population. We place each target on the lower part of quadrant C to minimize CTE trails. The galaxies have small angular sizes, so we should be able to choose a position on quadrant C that will avoid the columns compromised by droplets. At the time of Phase II submission, we were awaiting information about the location of columns affected by droplets that would allow us to consider tuning the positioning of the targets on quadrant C. We pack observations in both filters into a single orbit for each target. We want to maximize exposure time in the bluer filter, so we chose the minimum exposure time for the red side that allows parallel data dumps. We apply sub-pixel dithers to optimize sampling of the UVIS point spread function.
