These proposed IRAC data, along with joint HST imaging, will allow us to directly test key predictions of current models of cluster formation. These models posit that galaxy-galaxy merging drives the bursts of star formation and AGN activity seen in high redshift Spitzer studies of low-mass clusters, and predict the rate of such activity should be a function of total cluster mass. As clusters grow in mass (and hence velocity dispersion), the merging efficiency drops and the growth of the galaxy population, via both mergers and star formation, should cease. By measuring the cluster stellar mass function, as a function of both mass and morphological type, we will directly confirm or refute this model. We will also identify, on the basis of IRAC colors and HST morphologies, the AGN content in these clusters. We will thus test the prediction that the incidence of AGN should be higher in the lower mass clusters. Finally, we will measure the stellar mass fraction as a function of total mass, a crucial quantity in calibrating numerical cluster simulations that are key for cluster abundance cosmology. The scientific utility of the joint HST observations is described in the primary Technical Justification section above. The main advantage HST brings is its high spatial resolution, which we will use to (a) morphologically classify the cluster galaxy population and split it into early- and late-type galaxies, (b) deblend the IRAC data in the cluster cores, and (c) identify unresolved AGN. These tasks are best accomplished in the near IR, redward of the rest-frame 4000 A break, where morphological designations are unaffected by recent bursts of star formation, and where the "morphological K-correction" - a difference in morphologies in IRAC and HST bands due to color gradients - is minimal. We require 10 sigma photometry to obtain robust morphological classifications (see, e.g., Snyder et al. 2012) down to M*+ 3 to match our IRAC depth. Adopting a standard zf = 3 passive evolution model that describes cluster evolution at z < 1.3, we find M* = 20.4 (Vega) in the very sensitive, wide WFC3/F110W band. This corresponds to a surface brightness of 20.9 mag/arcsec2 within a half-light effective radius of re = 0.5", appropriate for z > 1 galaxies. We model our clusters in the WFC3 ETC as 2.5 Gyr old Bruzual and Charlot (2003) tau = 0.6 stellar populations observed at z = 1.2, which is consistent with the adopted value of M*. The cluster galaxies are assumed to have extended source diameters of 1", and photometry is extracted within circular regions of 0.5". With a 4-dither observation we find that reaching SNR = 10 at F110W = 23.9 requires an exposure time of 520s. To cover the full cluster out to r200 ~ 1 Mpc, we require a 2 x 2 map, which will also fully cover the IRAC footprint. The total request is therefore 1 orbit per cluster. The required data is already in-hand or scheduled for two clusters (MOO J1014+0038 and MOO J1142+1527) from the Perlmutter et al. supernova program (HST PID 13677). Our total HST/WFC3 request is therefore 12 orbits. No coordination between Spitzer and HST is needed, nor are there any special HST constraints. We will design our 2 x 2 map at any ORIENT permitted by available guide stars, and we can offset the centering by several arcseconds if required. 12 false false false false false false SUPPORTED CLUSTER OF GALAXIES HIGH REDSHIFT CLUSTER RICH CLUSTER J2000 J2000 CLUSTER OF GALAXIES HIGH REDSHIFT CLUSTER RICH CLUSTER J2000 J2000 CLUSTER OF GALAXIES HIGH REDSHIFT CLUSTER RICH CLUSTER J2000 J2000 CLUSTER OF GALAXIES HIGH REDSHIFT CLUSTER RICH CLUSTER J2000 J2000 CLUSTER OF GALAXIES HIGH REDSHIFT CLUSTER RICH CLUSTER J2000 J2000 CLUSTER OF GALAXIES HIGH REDSHIFT CLUSTER RICH CLUSTER J2000 J2000 CLUSTER OF GALAXIES HIGH REDSHIFT CLUSTER RICH CLUSTER J2000 J2000 CLUSTER OF GALAXIES HIGH REDSHIFT CLUSTER RICH CLUSTER J2000 J2000 CLUSTER OF GALAXIES HIGH REDSHIFT CLUSTER RICH CLUSTER J2000 J2000 CLUSTER OF GALAXIES HIGH REDSHIFT CLUSTER RICH CLUSTER J2000 J2000 CLUSTER OF GALAXIES HIGH REDSHIFT CLUSTER RICH CLUSTER J2000 J2000 CLUSTER OF GALAXIES HIGH REDSHIFT CLUSTER RICH CLUSTER J2000 J2000 WFC3/IR Imaging No No F110W WFC3/IR Imaging No No F110W WFC3/IR Imaging No No F110W WFC3/IR Imaging No No F110W WFC3/IR Imaging No No F110W WFC3/IR Imaging No No F110W WFC3/IR Imaging No No F110W WFC3/IR Imaging No No F110W WFC3/IR Imaging No No F110W WFC3/IR Imaging No No F110W WFC3/IR Imaging No No F110W WFC3/IR Imaging No No F110W POS-TARG DITHER 0.636 LINE false false 2 41.788 WFC3-IR-DITHER-LINE 2
