Faint Field Galaxies : an Explanation of the Faint Blue Excess Using Number Evolution Models

Pure luminosity evolution models for galaxies provide an unacceptable fit to the redshifts and colors of faint galaxies. In this paper we demonstrate, using HST morphological number counts derived both from the I814-band of WFPC2 in the Medium Deep Survey (MDS) and the Hubble Deep Field (HDF) and from the H1.6-band of NICMOS, and ground-based spectroscopic… CONTINUE READING
