Abstract:
The original analysis of the star formation history in the NICMOS deep
images of the northern Hubble Deep Field (NHDF) is extended to the
entire NHDF utilizing NICMOS and WFPC2 archival data. The roughly
constant star formation rate from redshifts 16 found in this study is
consistent with the original results. Star formation rates from this
study, Lyman break galaxies, and submillimeter observations are now in
concordance. The spike of star formation at redshift 2 due to two
ultraluminous IR galaxies in the small deep NICMOS field is smoothed
out in the larger area results presented here. The larger source base
of this study allows comparison with predictions from hierarchical
galaxy formation models. In general, the observation are consistent
with the predictions. The observed luminosity functions at redshifts
16 are presented for future comparisons with theoretical galaxy
evolution calculations. Mid- and far-infrared properties of the
sources are also calculated and compared with observations. A
candidate for the VLA source VLA 3651+1221 is discussed.
Description:
Observations utilized in this study are all from the Hubble Space
Telescope (HST) archives. The first set is the processed WFPC2 images
of the NHDF produced by Williams et al. (1996, Cat. J/AJ/112/1335).
The second set is the archival data from the NICMOS survey of the
entire NHDF by Dickinson (2000, Phil. Trans. R. Soc. London A., 358,
2001). The NICMOS F110W and F160W data were reprocessed
