Scientific paper

We have obtained the deepest slitless spectroscopic samples ever using the Hubble Space Telescope's Advanced Camera for Surveys, in two related projects, the "Grism ACS Program for Extragalactic Science" (GRAPES) and "Probing Evolution and Reionization Spectroscopically" (PEARS). In combination, these two programs obtained deep public spectroscopy of about 100 square arcminutes in the GOODS north and south fields. We are using these data to study galaxy evolution over a wide range of cosmic history. We are able to spectroscopically confirm Lyman break galaxies from redshift 4 to 6.5, down to AB magnitudes fainter than i=27.5. We use these samples to study a range of galaxy properties, including spatial clustering, Lyman alpha emitter fraction, and spatial extent of Lyman alpha emission.
