Scientific paper

The results of a photometric redshift study of galaxies in the Hubble Deep Field (HDF) are presented. The method of determining redshifts from broadband colors is described. Our photometric redshifts are tested both by direct verification with available HDF spectroscopic data and by comparisons of luminosity functions and luminosity densities with those obtained from z<1 spectroscopic redshift surveys. Evolution of the galaxy population is then studied over 0≲ z < 4. Brightening is seen in both the luminosity function and the luminosity density out to z~ 3; this brightening is followed by a decline in both at z>3. A population of z<0.5 star-forming dwarfs is observed to M_F450WAB=-11.
