Scientific paper

We propose to apply our optimal photometry and photometric redshift techniques to all available space- and ground-based observations of the UDF. We further propose to develop and apply an extension of our techniques to optimally detect and identify transient point sources {i.e. supernovae} using all available time- and wavelength-sampled observations of the UDF. Our primary scientific objectives are {1} to trace faint galaxies to low surface brightness limits in order to assess the effects of cosmological surface brightness dimming on the rest-frame ultraviolet luminosity density of the universe versus redshift and {2} to measure the supernova rate density versus magnitude and redshift to very faint magnitudes and very high redshifts.
