Motivated by both observational and theoretical developments, a new picture is emerging in which rapid but fairly smooth mass accretion and efficient secular processes play a major, if not dominant, role in the early evolution of massive galaxies. The proposed program will test this scenario through sensitive high-resolution WFC3/IR F160W and F110W imaging of 21 massive star-forming galaxies at z~2 with adaptive optics (AO) assisted VLT/SINFONI near-IR integral field spectroscopy. This is a truly unique sample, with detailed Halpha maps and kinematics resolved on ~1-2 kpc scales. WFC3/IR F160W+F110W imaging at similar resolution will provide the missing but crucial information on the bulk of stellar populations, from rest-frame optical continuum morphologies and colors optimized for measuring the age-sensitive Balmer/4000A break. This is essential to determine the detailed structure of galaxies, and the distribution of stellar mass, M/L ratio, and relative ages within them. The proposed data will directly tackle some of the most fundamental open issues concerning the formation of massive spheroids and disks, including the role of disk instabilities and minor/major merger events in the formation of bulges. The powerful combination of WFC3/IR imaging for the stellar component and SINFONI/AO data for the dynamics and on-going star formation will provide an unprecedented view of the stellar and dynamical evolution of galaxies at z~2, the epoch of major buildup of the most massive ellipticals, bulges, and thick disks.

PROGRAM GOALS: Our WFC3/IR program will map at high resolution the rest-frame optical emission of galaxies at redshift z ~ 2, which have Ha emission line kinematics and morphologies at similar resolution from our AO-assisted VLT/SINFONI near-IR integral field spectroscopy. The data will allow us to characterize the distribution of the stellar mass, M/L ratio, and stellar age within the galaxies on scales of ~ 1 kpc (~0.1"), matching well the spatial resolution of the SINFONI+AO data. Our science goals require: (1) sensitivity and optimal PSF sampling to characterize the properties of the more diffuse emission component of the galaxies and of superposed substructure, as well as to resolve possible nearby companions, on ~1-kpc scales (~0.1"), and (2) a filter combination that maximizes flux sensitivity for our faint targets and optimizes the measure of the age-sensitive Balmer/4000A spectral continuum break. STRATEGY: We have chosen the WFC3/IR F160W and F110W filters. For our galaxies at redshift 2 < z < 2.5, F160W best probes the emission redwards of the spectral break and the bulk of stellar mass, and F110W probes bluewards of the break. In addition to optimally bracketing the break, the F110W-F160W color minimizes dust extinction effects and the wide filter bandpasses maximize flux sensitivity. Given the importance of high resolution to our program, we intend to maximize the effective angular resolution by obtaining exposures in a dithered sequence with sub-integer pixel offsets, which may be drizzled together to both improve the effective resolution and help to eliminate cosmic rays and other artifacts from the data. Our program will image 21 targets. Given their brightnesses, our S/N requirements will be reached in ~ 5000s in F160W and ~2500s in F110W. The visibilities of the targets is 54min/orbit; accounting for overheads this means 2 orbits in F160W and 1 orbit in F110W. Four of the targets have sufficiently deep and high resolution F160W imaging from previous HST programs (with WFC3/IR and NICMOS/NIC2) but none of them has F110W imaging. This implies single-orbit observations through the F110W filter for all 21 targets, and two-orbit observations through the F160W filter for 17 targets. Because of the distribution of the targets over the sky, separate non-overlapping pointings are needed for each of them, leading to a total of 55 orbits. Each visit is planned so as to obtain all F110W, and F160W when required, observations of a given target. DITHERING, EXPOSURES, AND POINTINGS: We plan a minimum of 4 independent positions per object and filter to reduce the impact of instrumental artefacts and of cosmic rays. We use a customized WFC3-IR-DITHER-BOX-MIN dither pattern, preserving the sub-integer offsets for optimum PSF sampling but with modifications to the overall dither box size so as to dither over the targets (typical extent up to ~ 2-3" or ~ 15-25 pix), "blobs", and other bad pixels/regions. The sub-integer pixel offsets for the single-orbit F110W, and the first orbit F160W observations, ensure sampling by 1/2 pixel in each of the x and y directions. The dither pattern for the second orbit in F160W is similar but overall offset from the pattern of the first orbit by 1/4 pixel in both x and y. The parameters for WFC3-IR-DITHER-BOX-MIN are adjusted depending on the science target size and the presence of nearby bright objects. In total, four patterns are used. We choose the pointings so as to place each target close to the center of the WFC3 field of view, to reduce the impact of distortion and allow maximum flexibility in terms of orientation. We make use of the POS TARG parameters in the Target Position Requirements (at the Exposure-level Special Requirements) in order to offset slightly the dither pattern of each orbit away from the fiducial point (the array center for our adopted IR-FIX aperture). The pointings for the two F160W orbits place the target in diametrically opposite quadrants, and the pointing for F110W places it in a third quadrant. To calculate the corresponding POS TARG offsets in arcsec, we use the updated Apertures File from 01 July 2011. We use the MULTIACCUM readout mode with SPARS50 and NSAMP = 14. This choice maximizes the use of the visibility period during each orbit, allows parallel buffer dumps, and provides a sufficient number of non-destructive reads to further mitigate the impact of cosmic rays. We do not require special orientation constraints. N/A N/A Since our WFC3/IR exposures are long exposures of faint galaxy targets, please avoid if possible scheduling right after passage through SAA.
