Deep optical and near infrared images of the NHDF with HST provide information and place constraints on models of galaxy formation and evolution. Successful theories should match these observations. The constraints go from model and cosmology independent observations such as the apparent magnitude function to heavily cosmology and model dependent constraints such as the star formation history. All...

Tests and constraints on current theories of galaxy formation and evolution are presented. They are derived from observations of the Northern Hubble Deep Field with WFPC2 and NICMOS. Photometric redshifts, extinctions and spectral energy distributions are calculated for all objects in the field. The tests and constraints are derived from the output of this analysis. The tests of the predictions from...
