Exploring the high-redshift Universe
Unveiling the nature of bright z ~ 7 galaxies with HST

While deep Hubble Space Telescope surveys are ideal for selecting large sample of relatively faint z > 6 galaxies, to push to brighter magnitudes, deep, ground-based imaging on the degree-scale is required. Using the 2 square degrees of optical/near-infrared imaging in the UltraVISTA/COSMOS and UDS/SXDS fields we have selected samples of exceptionally bright z ~ 6 and 7 Lyman-break galaxies, placing the first limits on the bright-end of the galaxy luminosity function, and providing ideal candidates for detailed follow-up campaigns. I will present new results from our HST/WFC3 program to determine the morphologies and sizes of these highly star-forming z ~ 7 galaxies, which will also be targeted by ALMA in Cycle 3.
