Photometric Redshifts Applied to WFPC2 and NICMOS HDF Data


A photometric redshift analysis of optical and infrared images of the Northern Hubble Deep Field indicate a constant star formation rate for redshifts between 1 and 6. The small size of the field and small number of high redshift objects limits this finding to just the area of the NICMOS image. The photometric redshift technique is a modified version of chi square fits to observed and calculated galaxy spectral energy distribution templates.
