Scientific paper

This paper presents the first results from a deep spectroscopic survey of ≡200 galaxies measured using the fibre optic coupler at the Anglo-Australian Telescope. The authors discuss the strategy of their survey and observing/data reduction techniques. The redshift distribution observed is compared with model predictions and the authors test for luminosity evolution and a faint end extension of the galaxy luminosity function. They compare the faint galaxy spectra with those obtained in a magnitude-limited survey of bright galaxies. Evidence for strong star-formation activity is found in some of the galaxies. The authors discuss the implications of this result and present a new model of galaxy evolution, consistent with the count and redshift distributions at faint limits.
