Title: The highest resolution view of massive distant galaxies

Abstract: High resolution imaging of distant galaxies at near-infrared (rest-frame optical) wavelengths is essential if we are to understand how galaxies form, but HST is limited in resolution by the diffraction limit of its relatively small mirror. We have used the deep, wide-field SERVS/VIDEO near infrared surveys to pick out good guide star asterisms suitable for correction of the 1.5' GSAOI field using the GEMS MCAO system. With deep images in these fields, combined with photo-zs and other information from our unique multi-wavelength dataset we will be able to perform investigations of the morphologies of high redshift galaxies in samples selected in the near-infrared (tracing stellar mass at high-z) with unprecedented 0.08" resolution. In particular we will address the questions of the morphologies of z>3 galaxies, the size evolution of early type galaxies and the nature of the hosts of Herschel sources.
