5. Abstract

We request support to reduce and analyze the third deepest HST field imaged to date,
centered on the z=2.39 radio galaxy 53w002 and an associated cluster of possible
protogalactic clumps. We find that the summed images in F435W, F555W and F814W reach
within 0.5--1 mag of the depth of the Hubble Deep Field North. We will merge our
already fully reduced ground- based JHK imaging (to K=21.5) with the WFPC2 archival
data, and deep U band imaging we are obtaining with Keck+LRIS-B. We will also put in
a public archive the final reduced set of images, including our IR and U data. We
will obtain photometric redshifts for all detectable galaxies in the field, and
measure their morphologies and possible variability. These data products, along with
the complete multiwavelength set of photometry will permit us to construct the
redshift evolution of galaxy morphologies, and the global stellar mass and cosmic
star formation rate as a function of redshift.
