The Extreme Globular Cluster System of Abell 1689: The Ultimate Test of Universal Formation Efficiency The stellar masses of the most luminous galaxies poorly represent the masses of the halos in which they reside. However, recent studies of the very rich globular cluster (GC) populations in the centers of galaxy clusters point toward an apparently linear scaling of the number of GCs with the total core mass of the galaxy cluster. Thus, unlike for the stars in cD galaxies, GC formation in these systems appears to have proceeded with a roughly universal mass conversion efficiency. GCs are also distinct in that their spatial distributions are more extended than the starlight, and recent simulations suggest that they follow the mass density profile of the merged dark matter halos that formed stars at high redshift. To provide a definitive test of the universal efficiency hypothesis requires measuring the number of GCs in the most massive galaxy clusters, where the number should be a factor of 5 or more greater than seen in M87. Likewise, the relationship between GCs and mass density can only be tested in systems where the total mass and mass density are well-determined. Fortunately, the imaging power of HST brings the GC population of Abell 1689, the most extreme high-mass lensing cluster, into range. Estimates of the size of the A1689 GC population from available data suggest an unprecedented 100,000 GCs, but this number is based on the tip of the iceberg and is extremely uncertain. We propose to obtain the first accurate measurement of the number of GCs and their density profile in this extraordinary system - the most massive and most distant GC system ever studied - and thus make the ultimate test of the universal GC formation hypothesis. Our deep I-band image will also provide a stringent "null-detection" test of several known z>7 galaxy candidates and improve the mass model of the system by increasing the number of usable lensed background galaxies. Finally, we will take deep multi-band parallel observations with WFC3/IR to help in quantifying the abundance of rare faint red objects.
We will observe the central galaxy in Abell 1689 for 28 orbits with the F814W filter of the ACS/WFC. The observations will be split into seven visits of four orbits each. All visits are constrained to the same orientation, which is chosen to match the orientation of the existing multi-band ACS/WFC GTO data. Each orbit is split into two dithered exposures, and we also dither between orbits, using an 8-point dither line which moves the field in the y-direction by the width of the CCD gap between exposures. Successive visits have small POSTARG offsets in the x-direction to improve hot pixel removal. We do parallel observations with the WFC3/IR and WFC3/UVIS channels to search for high-redshift "dropout" galaxies with a deep series of exposures in a single parallel field. The WFC3 filters are only changed between visits; the filters for these parallel observations for visits 1-7 are: F606W, F098M, F105W, F125W, F160W, F606W, F098M, in that order.
