This will enable us to test whether the stars in ultra- faint galaxies--as a population--have been affected by Galactic tides. Most of the new dwarfs show signs of tidal interaction in ground-based photometry, several have measured ellipticities greater than ~0.5, and kinematics of a subset show velocity gradients. These ubiquitous hints for tidal effects among distant dwarfs is particularly surprising and suggestive. If most ultra-faint dwarfs are disturbed by tides, then recent tests of galaxy formation in the near field have unstable foundations. HST resolution provides an opportunity to assess whether tidal features (accompanied by tentative kinematic gradients) seen in ground-based observations of Hercules and Leo V are genuine or are instead clumps of compact background galaxies masquerading as stellar debris. In Hercules, a further test is possible: searching for a distance gradient along the stretched body of the galaxy. Parallel pointings will sample similar dwarf-centric radii away from the tidal features, assuring an unambiguous result. Whether we confirm or rule out the presence of stellar loss in these objects, the consequences are important--the origin of the ultra-faint dwarfs tells us the lower limit to both galaxy formation and the number of dark matter subhalos inhabiting the Milky Way. This program is only possible with HST: its exquisite resolution can separate compact galaxies from main sequence dwarf stars at faint magnitudes, which even the best multi-band ground-based schemes struggle with. ------------------------------------------------------------------------------------ Observations Description ------------------------ We request 24 orbits of HST/ACS to obtain imaging in F606W and F814W of fields in the ultra-faint dwarf galaxies Hercules and Leo V, the two distant Milky Way 15182( 11) - 16-Apr-2019 19:29:11 - [ 2] satellites with both tentative photometric signs of tidal disturbance and velocity gradients. In concert with parallel WFC3 observations, this imaging will enable us to test whether the stars in ultra-faint galaxies have been strongly affected by tides. We will target candidate debris streams identified in ground-based data with one or two Advanced Camera for Surveys/Wide Field Camera (ACS/WFC) pointings for each dwarf. Coordinated parallel observations with WFC3 at similar projected radii will provide control color-magnitude diagrams (CMDs) to ensure decisive positive or negative detections of tidal material, and to assess the impact of foreground star/background galaxy contaminants. Central pointings are needed to have CMDs to compare to the potential debris, and these data already exist in the HST archive at sufficient depths for both targets. For Leo V, we have simulated how many stars we expect to detect if the overdensities seen in the ground-based data are due entirely to tidal material or entirely due to unresolved galaxies. To make a 5-sigma detection of the overdensity, we need to detect 20-30 main sequence stars. We have chosen the standard F606W and F814W filter combination for their sensitivity and for consistency with the archived central pointing of Leo V (from GO-14770). By reaching depths of F606W=27.0 and F814W=26.5 we can ensure that we will detect at least 30 stars if the outlying Leo V field consists of tidal debris. For Hercules, If the tentative measurement of a velocity gradient along Hercules is correct (Aden et al. 2009; Deason et al. 2012), we can expect to measure a ~10 kpc distance gradient between our two ACS pointings, as predicted by the orbital calculations of Martin & Jin (2010), where Hercules is essentially a stellar over-density in a larger stream near apocenter. To model this scenario, we combined simulations of our ACS observations with the central archival data and a model of Hercules with a 10 kpc gradient. With data of the same quality as the central pointing, we can measure a gradient with an uncertainty of ~2 kpc, which should result in a robust 5-sigma detection if the gradient is in fact 10 kpc across our fields. The depth required here is greater than the depth required to verify the tidal debris (similar to that discussed for the Leo V case above), but will result in significant additional scientific gain by providing detailed information on the tidal disruption that could be occurring in Hercules ------------------------------------------------------------------------------------ 15182( 11) - 16-Apr-2019 19:29:11 - [ 3] TARGET LIST Fixed Targets ------------------------------------------------------------------------------------------------------------------------------------ Tar| Target | Target | Target |Coord | Radial | Flux data No | Name | Description | Position |Eqnx | Vel. | ------------------------------------------------------------------------------------------------------------------------------------ 1 HERCEAST GALAXY, DWARF RA=16H31M43.0056S, J2000 V = 14.6 +/- 0.2 SPHEROIDAL DEC=+12D43'43.82" Reference Frame: ICRS ------------------------------------------------------------------------------------------------------------------------------------ 2 HERCWEST GALAXY, DWARF RA=16H30M21.0071S, J2000 V = 14.6 +/- 0.2 SPHEROIDAL DEC=+12D51'43.77" Reference Frame: ICRS ------------------------------------------------------------------------------------------------------------------------------------ 3 LEOVNE GALAXY, DWARF RA=11H31M30.1368S, J2000 V = 16.0 +/- 0.2 SPHEROIDAL DEC=+02D18'21.00" Reference Frame: ICRS Comments: This target is centered on a stellar overdensity far from the center of the dwarf spheroidal, Leo V. ------------------------------------------------------------------------------------------------------------------------------------ 15182( 11) - 16-Apr-2019 19:29:11 - [ 4] Patterns ------------------------------------------------------------------------------------------------------------------------------------ Pattern_Number: 1 Primary_Pattern Secondary_Pattern Pattern_Type ACS-WFC-DITHER-BOX Pattern_Purpose DITHER Number_Of_Points 4 Point_Spacing 0.262 Line_Spacing 0.192 Coordinate_Frame POS-TARG Pattern_Orient 18.39 Angle_Between_Sides 68.14 Center_Pattern NO ------------------------------------------------------------------------------------------------------------------------------------ Pattern_Number: 2 Primary_Pattern Secondary_Pattern Pattern_Type ACS-WFC-DITHER-LINE Pattern_Purpose DITHER Number_Of_Points 2 Point_Spacing 0.149 Line_Spacing Coordinate_Frame POS-TARG Pattern_Orient 34.29 Angle_Between_Sides Center_Pattern NO ------------------------------------------------------------------------------------------------------------------------------------ 15182( 11) - 16-Apr-2019 19:29:11 - [ 5] Visit: 01 (LeoVNE Visit 1 -- F606W) Visit Requirements: ORIENT 65D TO 95 D On Hold Comments: Additional Comments: We are splitting our four orbits of Leo V NE into two visits, one for each filter.

The initial visit should have an ORIENT between 260 and 290 degrees. Coordinated parallels with WFC3 will be taken. The 2nd through 4th visits will have the same orientation as the initial visit. Visit 1 and Visit 3 for Herceast are 2-orbit visits, with a standard ACS-WFC-DITHER-BOX. Visit 2 and Visit 4 are 3-orbits, with a standard ACS-WFC-DITHER-BOX, and then a small-scale ACS-WFC-DITHER-LINE in the third orbit. This will ultimately give 5 orbits per filter, ten orbits total. This is a partial repeat of Visit 56. Only 1 orbit is needed.
