HST Frontier Fields - Observations of Abell S1063
Abstract
Using Director's Discretionary (DD) observing time, HST will undertake a revolutionary deep field observing program to peer deeper into the Universe than ever before and provide a first glimpse of JWST's universe. These Frontier Fields will combine the power of HST with the natural gravitational telescopes of high-magnification clusters of galaxies to produce the second-deepest observations of blank fields and the deepest observations of clusters and their lensed galaxies ever obtained. The primary science goals of the HST FF are (1) to reveal z~5-10 galaxy populations ~10-50 times intrinsically fainter than any presently known; (2) to solidify our understanding of the stellar masses and star-formation histories of galaxies at the earliest times; (3) provide the first statistically meaningful morphological characterization of z>5 galaxies; and (4) to find z>8 galaxies magnified sufficiently for spectroscopic followup and internal structure studies.
